Aiyoh, don't worry lah, this is actually quite normal at that age, babies' saliva glands start working more actively around 1 month, and they haven't learned to swallow properly yet, so the choking and drooling can seem scary but usually it's okay. That said, if your baby seems to be struggling a lot, having difficulty feeding, or if the vomiting seems excessive (not just wet burps), best to check with your paediatrician just to be safe and get your mind at ease. In the meantime, try to keep baby upright after feeds and burp gently, and maybe keep a cloth handy because yes, the drool will be real! You're doing fine, mama, this phase will pass soon.
