3 month old grazer

Laura

So my almost 4 month old is growing fine and healthy (15+lbs), but she is still eating every 2-3hrs sometimes more often and she is constantly hangry. She gets so hungry and fussy it makes her guzzle the bottle and she gets gassy and spits up a bit. The pediatrician said we'd talk solid foods at her 4 month appt in 2 weeks. The nurse I spoke to said she was hungry because she should eat more at a feedings (typically she only takes 3-4oz a feeding). She also said "she'll tell you when she's done." We give her more food when she is hungry, so in theory she has already told us when she is "done" she just loves snacking I guess.

Not sure if there is a good answer, but any mom-pros out there: Is there a way to encourage her to leave her grazing ways and eat more less often?
