I don't have any kids but i have 5 nieces and 2 nephews and i have watched them grow up. And from what iv noticed they didnt start smiling until 12 weeks. Some of them smiled sooner but it all depends on the child, its like saying they should all speak full sentences at 1 years old.. it takes time for some children. And i think that what they said is WAAY out of line! that is such an awful thing to say about a baby who was born a few weeks early. My youngest niece is 15 months old and she cant walk yet shes just started to crawl and the paeditrician (sp?) just said its because she was born early.. They need to take that into consideration.
