Please help! Long story short baby was diagnosed with milk allergy a few weeks ago, she’s been on elecare for 2 weeks. A week ago she was like a new baby, still a tiny bit fussy but barely at all!! Now ever since 3 days ago it’s like the gassiness is back?? She’s soooo fussy, almost colicky all day. We were sleeping 9-5/6 now I’m lucky if I get until 2 am before all hell breaks loose. She’ll only sleep on me if that and even then she’s fidgety and crying and gassy. Why did it come back?? I changed bottle nipples to size 2 (made no difference), tried gas drops, bicycle legs?? Idk what to do anymore!
