EBF - formula/gut flora

[Xjo1992x]

I have heard that giving an EBF baby formula can affect the gut flora.
Is this still the case when the baby has already started on solids?
We are going away for a night next week and I can't get him to take expressed milk from a bottle (he tastes the milk and screams for the boob). He will take juice/water from a bottle or cup though so I'm hoping he will take formula.
I don't want to give it however if it will ruin all the hard work I have put in with the breastmilk.
I also don't want to put him off the boob as I'd like to continue b'feeding for a few more months yet
(He is 6 months old)

No I think the guy flora theory (and I believe it is only theory atm) would be for a “virgin guy”... not once solids were started.

No, and this is a ridiculous theory to begin with. Most babies have medicine orally by 6 months or almost none will ever have a truly ‘virgin gut’.

I’m Breadtfeeding but have been on antibiotics. Surely that’s worst!
Antibiotics are going to kill off any happy gut flora!

As PP have said, "virgin gut" theory stops once solids are introduced

Agreed. Formula is just a food, like solids. It will make no difference at this stage.

Have you tried to have baby take bottle of expressed milk while you are out of the house? One of my babies never would take a bottle from me but took from other people if I was not home.

‘Virgin gut’ is a stupid term
