Needing advise

If you’re breastfeeding, eat a whole can of mandarin oranges and then feed as normal. Idk why it works but it does lol

Have you tried gas drops? I use little remedies brand with every feed and it's helped my boy so much. He used to scream and kick everytime he had to pass wind, but now he's 7 weeks and doing worlds better

Frida baby Windi….or any similar dupe on Amazon

If you’re comfortable then try gently massaging tummy and raising legs / bicycle like movements too.
Also 20 mins upright position post feed would help.

If they are bottle fed Have you tried a different brand of bottle by any chance? I had to exact same problem with nothing I did seem to work and it turned out the teat Just wasn’t right for him.

Windi sticks and mylicon worked wonders for us.

Have you tried colic drops my 2 month old use to scream due to trapped wind after a feed works wonders for us we also run our index finger up each side of his spine to help move the trapped wind
