weaning- how much vomiting is normal?

[parentsvsPIL]

Weaning DS at 6 mo. First week - banana & baby rice go down well & stay down. However sweet potato & potato both reproducibly result in vomiting 1-2 hours later. It's usually only one vomit and it's not projectile but it is quite a lot and reasonably forceful.

I've been posting a lot on the allergy boards as DS has allergic proctocolitis. What alerted us to it was him reacting to me eating tomatoes; however I have been eating potato with no particular issues, so I thought it'd be OK.

Allergist friend says actual allergy to nightshades and sweet potato are both very rare - so do I treat this as allergy (wait a month and try again; if still vomiting leave it for 6 months) or do I assume it will get better and DS just has a sensitive tummy and I should keep feeding him things that initially make him sick?

I can read the allergy literature but don't konw much about weaning (and allergist friend clearly didn't do much feeding of his kids at this age as he also has no idea what's normal in weaning!)

That's a difficult one and I'm not sure I know the answer. I'd do Weaning the old way, introduce one new food every 3 or 4 days. You might be best giving solids at breakfast only, just to give LO time to digest it before bed.

Thanks. We are giving him new foods at breakfast time and previously-introduced-ok food later, which effectively means lunch is baby rice, banana and ABC spread.

Allergist friend is encouraging us to follow EAT protocol, and evidence for introducing & regularly feeding diverse potential allergens is good... but poor DS has had 2 days of awful diarrhoea with chunks of blood, after introducing yoghurt & egg.

If he's had 2 days of diarrhoea, if it was me I'd just stick to milk for the next two or three days and let him recover.

yep, i agree. Seems to be clearing up fairly quickly, but a day or two off the tough new stuff seems like the right thing to do.
