Baby food and formula??

Kira

So I buy 5 things of formula for the month, but my daughter has recently started eating the whole thing of the Gerber baby food does that mean I can buy less formula like 3 things and baby food because she'll eat the formula and then an hour before her next bottle I give her baby food which holds her off for a bit. Or is it just a thing you give once a day?

She's 5 and a half months old.

She can open her mouth for food and swallows.
