Yesterday we had a really informal survey on our Facebook page to try to pinpoint the average number of words that babies can sign at each stage in their development. The sample is really small and i will update it as more members of the community contribute. For now, here is the chart:
Key findings so far are as follows:
- Many babies will have up to 5 signs between 6-12 months.
- Between 12-18 months you are likely to see their vocabulary increase as high as 30 signs.
- So far we have not received any reports of little signers younger than 6 months old. If you have one please share with us.
