just realised bottles not rinsed properly

[magnummum]

as 6 month old was finishing off her bottle and gave it a good shake it was very bubbly! Have I poisoned her or is she unlikely to suffer any ill effects?

Tummyache?

I would ring NHS direct to be on the safe side.

some of the formula milks do go bubbly when you shake them. I am sure your lo will be fine
