H will be 9 weeks old on Friday. She can smile, but she doesn't do so very often and I have to REALLY work at it. She doesn't find tickling and general silliness very funny, but if I really grin in her face at the right time of day, she will smile back. Her pediatrician isn't worried because she does smile sometimes...she says she is just a "serious" baby. She is pretty laid back...not at all fussy and sleeps a lot. Seems content most of the time. She has great eye contact and tracks really well.

Anyone else have a not-so-smiley baby??? Did they smile more as they it older? I am trying not to worry, but I can't help it! Her older sister started smiling a lot at 4 weeks!

Here's an example of a hard to come by smile....
