My 3 month old baby is vomiting after giving formula milk after 2 hrs of feeding? what to do? How much gap I have to give inbetween formula and breast fed

A. Mam after 60 days of birth you are advised to feed your child on demand and formula as much heavier as compared to regular breast milk so if you’re fed now then you should wait even the child take 3 to 3 1/2 hours to demand for a free it’s completely alright then you feed the child as this way you will save your child from overfeeding and extra vomiting
