HELP - Baby drinking less formula milk?.

[Flowers31]

Hiya

My 4 month baby has been drinking less formula milk for the last 3 days. Usually he drinks about 25-30 ounces however now he's drinking under 20 ounces. He just keeps pushing the bottle out and starts crying and getting gas.

He doesn't have a fever and is still playful etc. I'm just really worried about his milk intake. Does anybody have any advice. Thanks in advance x

Could he be teething?

Maybe the milk doesn't suit him? Could be making him bloat. Also he might be thirsty?

I'd give him a dose of ibruprofen and see if that encourages him. If he drinks the bottle after that, you'll know he's got something that's been hurting him.
