Teaching your infant to sign is more complicated than most people assume
I spent about eight months working through baby sign language with my first child before I stopped treating it like a language class and started treating it like a communication compromise. The gap between "the baby knows the sign" and "the baby uses the sign when they want something" is genuinely huge, and most parents don't realize it until they're exhausted from guessing. Baby Sign Language For More is an app that structures these signs into a curriculum. It's not the only one out there, but it was the one I ended up using consistently because the daily streak feature forced me to actually practice rather than watch three videos and then forget about it for two weeks. The core premise is simple: you introduce about two to four new signs per week alongside the spoken word, repeat them during routine activities, and wait for the baby to mimic the gesture. The actual mechanics work like this. You pick a sign, say the word clearly while making the gesture, and do it in context. So when you're pouring milk, you say "more" and make the sign by tapping your fingertips together. You do it every single time the baby asks for milk or finishes their bottle. The repetition in context is the part that matters. A baby doesn't learn that a hand shape means something because you showed them the hand shape in isolation. They learn it because you paired it with an actual situation they care about.
Here's where most people go wrong. They move too fast. The app itself has a default pace that's reasonable, but I watched a lot of parents skip ahead because the baby seemed to understand when they wanted something. What they didn't realize was that the baby had already learned to read their cues — a glance toward the bottle, a cry pattern, a reaching motion. The baby wasn't signing. They were being guessed at. This is the "illusory comprehension" problem, and it's why some babies seem to know signs at five months and then never produce one voluntarily until twelve or later.
Getting Started With Baby Sign Language For More
Start with just two signs. Milk and more are the standard recommendations because they map onto needs the baby expresses constantly. Don't add break, hungry, or all done until those first two are being used reliably across at least a week of normal feeding routines. The app's lesson structure handles the progression for you, but the rule of waiting applies even if the app suggests moving forward faster. The downloadable content in the app includes printable cue cards and a sign reference sheet. I found the printed cards useful for placing around the house — kitchen, living room, crib area — as visual reminders for the adults in the household. Babies pick up signs faster when everyone in the house is using them consistently. If one caregiver signs and another doesn't, the baby learns to sign only with the person who reinforces it. I hit a specific wall around month four of practice. My child would perform the sign for milk about half the time, but on the other half they'd just cry and point. I was frustrated because the data from the app showed they'd mastered the sign. The workaround was figuring out that the sign was context-dependent in a way I hadn't accounted for. They signed milk when they were mildly hungry but escalated to crying before they could remember the motor pattern when they were very hungry. So I started signing the word right at the first hint of fussiness, before the cry started, and that closed the gap. The sign became reliable within another three weeks.

The app tracks which signs have been practiced and which haven't. I used the history log to catch the fact that I was only doing morning sessions. Evening sessions mattered just as much because that's when the baby was most tired and most likely to need communication shortcuts. Switching to twice-daily practice roughly doubled the rate of spontaneous signing. There are a few things the app doesn't cover well. The first is regional variation in signs. Different communities use slightly different gestures for the same word, and the app sticks to one set. That's fine as long as you're consistent, but if you run into family members who use alternate signs, your baby might get confused. Keep it simple: stick to one system and note the variations for the adults. The second limitation is that the app doesn't account for developmental differences in motor control. Some babies can reproduce fine motor signs by eight months. Others aren't physically capable until ten or eleven months, and that's normal. The app's age-based suggestions can make parents worry when a baby isn't meeting the timeline. They don't need to. The milestone is communication, not compliance with a schedule.
The third issue is that signing alone doesn't replace speech development. These are parallel systems. A baby who signs still needs to hear spoken language extensively. If the goal is reducing frustration in the pre-verbal period, baby sign language works reasonably well for most families. If the expectation is that it will accelerate talking or substitute for it, that's not how it functions. Some studies suggest a slight vocabulary advantage in toddlerhood for children who were signed with, but the effect size is small and the research is mixed. The app itself is subscription-based after a free trial period. The weekly cost is low enough that I didn't stress about it, but if you're going to use it, commit to using it daily rather than subscribing and letting the streak die. The algorithm rewards consistency. Miss a week and the progress tracking becomes less useful because the app can't establish a baseline from sporadic usage. For the actual download, it's available on both the App Store and Google Play under "Baby Sign Language For More." The website lists the pricing tiers if you want to compare them before committing. I'd recommend starting with the free trial period and honestly assessing whether you'll use it daily. If you're the kind of parent who reads about parenting methods and then moves on, the app won't help much. It only works if you're willing to repeat the same two or three signs twenty times a day for several weeks.
