This is a normal thing. This is colic. U can add collicaid drops for 3-5 days. U have to burp after feeds. U can keep the baby in prone position for 10 mins. Thanks.

You can try simethicone drops. One drop every 6 hours should work. Often this gassiness and discomfort are normal part of a child growing up. It is a way his body and muscles are learning to pass stool and gas. Simethicone helps with reducing the gas produced and can help with symptoms. I This gets better with time.

This is normal for the baby. Burping should be done after every feed. Gently move the baby leg in bicycycling motion.Put the baby in prone position with face to one side also can relieve gas

Burping should be done properly post feedings

It’s normal for babies. Nothing much to worry. Give baby exclusive mother milk and avoid formula milk.

This is totally normal only

Mother should drink more water

Greetings Straining and crying before passing soft stools is typical for a three-month-old.This condition is called infant dyschezia, where babies learn muscle coordination to poop.To help ease gas, practice frequent tummy time and gentle abdominal massages.You can also move the baby's legs gently in a cycling motion to relieve pressure.
