My 4 month old wakes up screaming, what could be wrong?

She mite only be in bed asleep 10mins she wakes up roaring, ill get her back to sleep but she will wake like this every 15mins for over 2hrs, then she settles.

sometimes that just is the way it is with babys. nothing to be terribley conserned with. you can try warm bottle, with a little bit of rice cereal in it. sometimes that will help infants sleep better.

she might have bad dreams... I don't know if babys that little dream but that could be it. my friends daughter woke up screaming a couple times she is two we think she has a bad dream.

Nightmares.
My son has them all the time- sometimes they're triggered by a tummy ache though- so I give him some gripe water and burp him and he's usually just fine after that.

She might be having night terrors. If it continues for several weeks, I highly suggest taking her to the doctor. If it doesn't, she might just be having nightmares.

she either could be hungry or teething. my baby was teething at 4months and I had to get teething tablets you give her two or three they are all natural and she will be fine after you give them to her

Night Terrors, for sure.
Just pick her up and hold her. Get her that soothing baby night time wash. It is what was wrong with my little 2nd cousin Kayleen only hers were so bad she would make herself vomit. Give her a bath with that soap and give her a warm bottle and maybe put some soothing music on, sing her to sleep, or get a mobile to play music. It helped Kayleen. If it continues, go take her to a psycologist or her pediatrician. Hope I helped beacause I know when I was babysitting Kayleen over-night, it was difficult and scary and I did those things and she slept peacfully for the rest of the night!

4 month old is too early to have night terrors, she could be colic, have reflux, I would talk to your doctor about it
