Dr. appt

Today we had our 15 month appt. The Dr. thought she looked great, but she did say I need to feed her more, she has dropped from 70% to 40% for her weight. But she said Gwen's iron level is great, better than what most kids at her age have.
The vital stats:
Weight: 22 lbs 6 oz 40%
Height: 30.75 in 60%
That is a 1lb 6oz increase in weight and a 1.25 in increase in height.
At the appt, Gwen pulled all the books out of the box and then crawled in there, when the nurse came in she thought that was so cute she called everyone in to look at her. Gwen got embarrassed by this and started crying. She got 3 shots today and is kind of fussy, is that because of the shots or because we didn't make it to our stroller group and are stuck inside because of the drizzly weather?
