If your 13mo:
- wasn't waving, clapping, or pointing
- didn't follow basic instructions (although has just started giving me what he's holding if I put my hand out and say 'ta')
- has only said "ba" since about 11mo and has never said any other babbling sounds
- only started using a pincer grip at 1yo
- is quite fidgety and definitely not one of those relaxed babies
Would you worry?
