Hi,
My DD is 5 weeks old and I took her to my GP today. He asked me if she has started smiling yet, to which I replied that she hasn't. (She smiles when she has wind, but it's not a social/receptive smile). He said he would be concerned if she doesn't smile by the time she is 8 weeks. What would it mean if she hasn't smiled by then? Is it a sign of something?
Thanks
