Does similac cause phlegm in your babies?

I think most formula milk cause Phlegm is the long run. I have heard people telling me similac is heaty. My gal was on enfamil and I find it too rich too. Once I change her to enfamil her constipation eased. For similac My nieces drink it and once the tin is opened I can smell the sweetness

Not that I hear of and nope. Fm can be heaty tho so u may consider putting an additional 10ml of water if u are making a 90ml or more feed and if u mainly give ur baby fm. If baby is older than 6 months or is on solids, also give more water
