My Baby is 4 months old now but he was born in 32 weeks. And he's bottle fed mostly. I'm curious to know when will he be able to recognize his mothe, till now I'm unsure whether he can recognize his mother yet. He's mostly taken care by me or by my mother. He's more effectively handled by my mother.And what development activities should I expect at this age. He's smiling at all the faces and coos a little. Are his milestones development according to his age?
