Colic in 2w old baby?

Sung

Hi

My daughter is just over 2w old now. She’s recently started crying like mad, arching arching her back and going all red from around 6/7pm till 10/11pm. She seems to constantly want to feed but I worry about over feeding her as she has vomited a few times in the past week or so. She settles a bit when I hold her upright with slow rocking but it doesn’t seem to help for long.

How do you know when your baby gets colic? What helped you guys??

Please share your wisdom as I’m really being drained..
