2 month old

Kit

My baby girl is 2 months almost 3 in about 2 weeks. These past few weeks she’s changed so much! a week before she turned 2 months she started cooing and getting more movement and now she can’t stay still lol Now where I’m having problems at now is her sleeping schedule is wayyy off track plus she just started staying up 2 hours in between her feedings. I’m so exhausted 😭 I need tips!! Help please. S/N She’s always throwing up after every feeding, it’s not a lot but it’s after EVERY feeding .. is this normal? It started when she switched to formula (For about a month 1/2 now) Does she need to switch formulas?
