- At 24 months, the Baby Signs® babies were on average talking more like 27 or 28 month olds.
This represents more than a three-month advantage over the non- Baby Signs® babies. In addition, the 24 month old Baby Signs® babies were putting together significantly longer sentences.
At 36 months, Baby Signs® babies on average were talking like 47 month olds, putting them almost a full year ahead of their average age-mates.
- Eight year olds who had been Baby Signs® babies scored an average of 12 points higher in IQ than their non-signing peers.
Using Baby Signs® helps children develop both language and cognitive skills.
