Colic or something else?

Yes that is very normal my little miss was colic its hell hun I'm sorry. I have heard laying the baby on her back and pushing up on her legs into her belly, but it never worked for me. Mine only slept in her swing for months. You might wanna try ever so lightly pushing on her belly when you are burping her that works for me. And colic is painful for a baby. If you ever get overwhelmed and need a brake take one, that little girl is going to cry in your arms or in her bed. Good luck and try and sleep when you can because the next few months are going to be hell.
