Girls, my little one gets very fussy while breastfeeding, she cries, turns red (it seems like gas because there's sounds and she lets out air, although it doesn't get better after that), because of this she releases the breast, can't hold on, and ends up sucking for about 5 minutes, then she doesn't want anymore ((mostly everything gets worse at night, and since she naturally isn't fed every 5 minutes, she asks for the breast every half hour and so on). I don't even know what to do, does gas appear only during breastfeeding? or could it be something else? maybe someone has had this too?
