First time mum here, I have an 8 week old daughter and at around 3 weeks old she started crying an awful lot, it started for like 3-4 hours in the evening she would scream and was very hard to console, she also struggles to poop, I switched her formula to comfort for colic & constipation and had a whole week of a happy baby, but now the crying is back and she cries from 12pm until 9-10pm at night for a few days in a row then will have a few good days again, I love my baby but it’s so exhausting and I can’t even bring her out when she’s crying like that, is it colic or is she sick? There haven’t been any issues at any check ups .. feeling so helpless
