My baby is 4.6 kg now being 5 month n 12 days, he vomits milk after 15 min of feeding, we try to burp but he is not instead he keeps fingers immediately n start licking, pls to suggest on this

A. Teething could be happening with your child so I think that is why your child is having discomfort and putting fingers into the mouth all the time it is a good time for you to introduce her teether to your child and also please check with your doctor because it seems like your child is little underweight
