DD (6mo) just Vomited straight after meal- Why?

[whelk]

dd2 is allergic to milk (discovered one week ago after exclusive bf to 6mo- so Im feeling a bit raw) and now I'm absolutely paranoid about other potential allergies.
I just fed her quite lumpy carrot, potato and peas, followed by pears all of which she has had at least twice before.
She just brought it all back up but there was no rash or other allergy symptoms.
She doesn't seem to be poorly and she is not a sicky baby. It was quite lumpy and she wasn't very enthusiastic about it but wasn't refusing iyswim
Any ideas?

It just happens sometimes, it's not always an allergy thing. They don't have the same well developed stomach we have, it's very easy for them to throw up at the drop of a hat.

thank you for replying. im so paranoid especially as dd1 has allergies too. i am really hating the stress of weaning!

Babies have a much more sensitive gag reflex than adults - my 2 used to gag when they were getting used to lumps, and sometimes they'd bring back most of their meal up.
It got better as they got used to swallowing lumps.
HV once told me that where adults gag reflex is based at the back of the tongue, babies are much further forward on the tongue, making them vomit more easily. It goes further back as they get older.
