L.G.
I breast fed both my son & daughter, & I found that my daughter ate much more often. she was the 2nd child, and I worried that something might be wrong. But after I spoke to several Moms & my doctor, I realized that if she awoke then she was hungry, & if she did not awake this meant that she was most likely not hungry. I felt as though I was not feeding her enough- but I realized that she was healthy & this was the main point the physician made; she'll let you know, & she is a very healthy baby :) As Moms we worry-my babies are 13 1/2 & 15 1/2 now! I miss when they were babies!
I would do what feels right. This time goes so fast, & then they're all grown up.
I hope this helps :) Take care...
