My baby will be 7 weeks old in two days, for the past couple days and nights she has been very fussy unless she has the boob and sometimes even fusses on the boob. She gets the boob and then spits it out, cries, repeat for freaking hours, what the hell does that mean?? Is it normal? She will move around and pull on my boob. I feel like she's not getting enough and I want to make her a bottle. Should it?
