I know this is a breastfeeding group but wondering if I could get some advice.

I’m trying to ween my 6 month old onto formula. Ever since he was born he has had one bottle of formula before bed and has always been fine with it. I have recently been giving him more formula in the day as I’m trying to ween him off breast milk. But he has started being sick.. a lot. He’s been sick 5 times today and it looks like curdled milk. He is totally himself and doesn’t cry when he’s sick.

I think he may be teething also so I’m not sure if this amount of sick is normal or not? Is this him getting used to formula or is his body rejecting it? Should I go back to breastfeeding for now?

I’m considering taking him to the doctors on Monday.

Any advice would be super appreciated. Thank you!!
