Thanks for your query.
Regurgitation is seen commonly seen in 40% of babies .
I advise you to give small feeds more frequently.
Held baby against shoulder for 20 to 30 minutes.
Keep head elevated to 45 degrees while sleeping.
Give exclusive breast feeding till 6 months of age.
Regarding gas formation you can give neopeptine
drops after consulting your doctor.
Wishing your baby good health.
