Erratic milk intake at daycare

joie12

DD is very happily eating three "meals" of solids a day. She usually drinks 3-4 oz at a time at daycare, about 3 times a day. Recently, that's been going down, and she's only taking in 1-2 oz at a time before throwing the bottle. Those days, she does seem to nurse a little more in the evenings. 

Is this related to the solids? Normal for her age (8 mos)?
