I seriously don’t know how to help my daughter anymore!!

She’s 14.5 months old and she literally cries and whines ALL DAY EVERY DAY. She has been to the doctor and the er twice for a cold and croup but that’s been two weeks since the last visit. She had one tooth that was taking a while to come in but it finally broke through, so I don’t think that’s why.

Lately she hasn’t wanted to eat as much and she won’t take a bottle anymore. Also, she nurses throughout the entire night. I don’t know how else to help her!

If I tell the doctor that I think something is seriously wrong with her, they won’t take me seriously. She has an appointment in a couple days to discuss this but until then, I’m lost. The only time she is not screaming is when she’s nursing. She is completely inconsolable 98% of the time. I’m worried for her and I’m also kind of losing my mind lol. Has anyone experienced this with a toddler her age?? (She hardly ever cried at all up until about 4 months and then still didn’t cry a lot, so this is totally new. And no health problems that we know of).

My mom thinks that it might be because she doesn’t sleep cuz she’s too busy trying to nurse or that she has a sleep disorder that’s making her act this way. Should I sleep train her? Sorry for the long post I just seriously am clueless as to what could be wrong with her.
