Well I'm not too sure about the first 1 but my daughter kicks ALL the time during b/feeding!! Cause she reach the edge of the chair she presses up against it. She likes to keep busy while feeding!!

She doesn't head butt me while feeding but I have seen her do it and my best friend's boy went through a stage where he would throw his head back against the wall - thought it was hilarious!! I think I actually read somewhere that head butting is normal! I guess like anything they are figuring out what they can do. My DD is happy watching her hands move slowly in front of her for a few minutes - it's like she is amazed at what is on the end of her arms!

She LOVES sticking her tongue out - for minutes at a time and I wonder why her mouth doesn't go dry - I have seen HEAPS of babies do this - another experiment.

TRy not to stress but if you are worried about anything ask you MCHN at next appointment. Or google it - that's what I do but I think your son sounds pretty normal to me!
