3 month old cries through bottle feeding.

Mom • My name is Raschel. I`m married and have a wonderful 4 year old son and a beautiful rainbow baby girl born nov 2016.
I'm having such a hard time feeding my 3 month old. She cries almost the whole time while feeding. She acts like there is gas trapped but I can never get her to give me a good burp. They are usually just little wet burps. Iv tried using a different bottle but she did not like it. It's making feeding her so stressful
