25 day old crying when breastfeeding

adriana

So we've been having troubles for a while now. Mainly at night time ...weird. She eats and eats until she spits up. If I dont feed her she starts crying. So I just do. She has been gaining weight so the doctor doesn't see anything wrong with it. NOW, everytime she's feeding (at night time) she will suddently start fussing and kicking and it slowly turns into a scream then a loud cry. I always try to burp her, she does burp after but after i put her back she starts screaming again. Sometimes she'll have her mouth open on my nipple but wont latch on (while fussing). It's like she forgets how to breastfeed for a second. Then latches on and starts crying. What could be wrong? She has an appt tomorrow so I will ask. Has anyone else experienced this?
