My 5 wk old has started what I assume is the 'fussy period' this week. It was like a switch turned on and she has been crying and difficult to calm down in the evenings and in the mornings. Overall, she is just more fussy, and she was an angel baby until now- she rarely cried. She has gas way more than normal- I think she must be passing gas 20 times a day! They are loud- she doesn't cry, but I wonder if the screaming/crying is because of a tummy ache? My question is, is the fussiness that peaks around 6 weeks related to gas or is it just general fussiness? I don't know what to do- I stopped all dairy today- I was allergic to milk as a child so maybe that is bothering her. Also, she hasn't pooped yesterday or today.... any thoughts???
