My son is a month old and I had same issues. Try to breastfeed him for 5 mins and burp him. Then try to give him milk again for 5 mins and burp. As per my doctor, mother's food also effects baby as baby might not be able to digest mother's milk so he spits out. Drink 2-3 glasses of milk and eat more n more fruits. Try to avoid food that leads to acidity or indigestion. It will help ur baby to digest milk easily. For tight stomach relief, massage clockwise around the naval with coconut or mustard oil when you massage baby before bath, baby will get relief from gas and poo count will increase.

thanks for ur answer. .

burp in between the feeds. feed half the time baby normally does, burp him and feed again... poop decrease is normal, don't go by poop count, go by pee count.. that should be 6-7 a day...
