Hi - 10 week old is formula fed on SMA Althera due to CMPA. He's posseting/being sick a lot- unsure if it's because of the formula, the allergy or just what he's like! It isn't cause for concern health wise but I'm wondering if it can be reduced so - any tips?! I tried thickener but it didn't make a difference and the health visitor told me not to (I didn't ask why). Wondering if I could be doing more with feeding position, winding technique, anything else?
