Hi there,

I was hoping I might be able to gain a few opinions on some behaviors I have noticed in my six month old. He is a twin, and whilst I know I shouldn't compare, there are real differences between the two which has lately being causing me real concern!
I know that six months is still so early, but I can't stop thinking that there might be an issue, and I am finding myself constantly watching him for signs.

A couple of things I have noticed are

not making a huge amount of eye contact- when he does he does smile, although usually just looks away. He does seek me out with his eyes, but just doesn't maintain for long periods of time.
Tapping his left foot- usually when sitting in his bouncer
Fiddling with things- tags on things etc
Playing with his ears- no other signs of ear infection or teething
No real 'talking'- doesn't imitate sounds. Plenty of laughing, squealing etc
Not answering to name

Otherwise he seems to be doing ok. Eating well, tolerating solids, sleeping and napping well, occasionally rolling over, starting to sit.

Im not sure if this is normal, but his brother is just so outgoing, talkative and in your face that there is a stark contrast.

Any opinions much appreciated!
