Soy milk should only be given on the advice of a doctor, pease don't offer it again until a doctor has ok'd it. If you think she has allergies, you need to take her to the GP and get some proper allergy testing. Once the GP knows which allergies your dd has, they should be able to prescribe some formula for you.
As for the solids, yes it's perfectly normal and nothing to worry about.
Regarding your plans on returning to work, I'd talk through reducing feeds and introducing solids with a BFC, have you got the helpline numbers?
Hi. My 6 month old DD has been exclusively BF since a few weeks after birth. She now weighs a ton and my back is having serious trouble with the BFing. She also starts nursery in August and I have to be away from her for a whole day in June. Hence, I thought it might be a good thing to wean her off me and ont formula plus some food. I don't seem to be able to express milk for her.
On the formula from we discovered that she seems to be allergic (blood in poo, rash) to regular formula, so now we are trying soya milk (which even I thinks smells vile). She won't take a bottle at all, but will take water (but not milk) from a free flow Tommy Tippee. I got her to take some soya milk once when I heated it up to the max I dared have it, but as soon as it cooled slightly she was having none of it.
On the food front - she started well, and still plays with/occasionally sucks on or gums big food that she can pick up, but anything puree'd has become a no-go area (she clamps her jaw shut and does the whole crying-with-a-closed-mouth thing if she sees a baby spoon heading her way).
So - my questions really are: 1. Any advice for getting her to accept the soya milk? 2. Is it OK for her not to be really having solids? The other babies I know are guzzling food down like there is a famine on, but DD is having none of it.
