Fussy when breastfeeding

Darlene

Lately my 5 week old baby girl has been wanting to nurse before its time but then i put her on my breast and she fusses and kicks her feet and pops on and off a lot. To me it seems like she is overeating and just wants to nurse to sleep but its hard to say. If i let her do this she ends up spitting up a lot and just seems to want more. Anyone else experience this?
