Make sure to burp her after every feed. You can also do the bicycle motion to her legs to help release the gas. My babygirl would cry murder the first few weeks and we figured it was due to colic. Couldn’t even get proper sleep and I was awake the entire night on most days. Now at 2mths, she sleeps better. I think it’s just a phase and it will pass. Just got to have lots of patience too.
