Question for all mama's.

Brittany • Married to my best friend and we have two beautiful children who are 21 months apart.

I just had my second baby 8 weeks ago. I was induced at 38 weeks.

She hardly ever smiles. When my oldest was a newborn he was smiling at 3 weeks.

I know every baby develops differently, but she will be 2 months old on the 5th. Shouldn't she be smiling by now?
