Today starting at around 4 or 5 pm aidan has been so fussy and crying so much no matter what we do! He is 4 months and he has started to be a lot more active, laughing and smiling but today its like anything we do just doesn't sooth him he has had a few spit ups and burped A LOT more than he has been, but he has also overeat and made himself sick I believe. His body feels really tight? Like theres air in it. if we lay him down or sit him in his swing he cries so bad almost like a highpitched whimper help me!
