My NB is 4 weeks old and has been TBF thus far. Today I introduced Bellamy's formula for the first time - and realise she has some allergic reaction in the form of red spots. Is baby allergic to Bellamy's or is this just initial reaction to formula in general?

Maybe you can observe if the rashes go away after a while. Or try another formula to compare if there are similar symptoms. Generally, if baby is really allergic to the formula, he will display the following: 1) Dry, itchy, flaky patches of skin (eczema) often behind the knees or in the crooks of elbows. 2) Hives 3) Swollen lips or mouth (call 995 if you see troubled breathing) 4) A red ring around the anus that doesn’t seem to respond to diaper rash remedies 5) Straining to pass gas, very fussy and irritable after eating. http://incredibleinfant.com/infant-formula/baby-formula-allergy-symptoms/
