Lactose free formula transition to regular first infant milk formula

Hello
Can any offer an insight on how you transitioned your baby from a lactose free formula (or equivalent) to regular first infant formula?

My baby is almost 6 months and has been on lactose free formula since she was 2 months due to suffering the typical lactose intolerance symptoms. The LF formula helped a lot.

Baby is now at a point where she is well enough to try introducing normal formula (she had many episodes of bronchiolitis over her first winter so it was thought best to not introduce anything that could upset her more).

I've had opinions from 2 health visitors, one of which said to try swapping out a whole bottle each day until all her bottles are all regular first infant formula and if the intolerance symptoms come back then go straight back to LF formula and wait another 2 weeks to try again. The the other HV said to take the plunge and just change all bottles at once.

Anyone have any experience of any other ways to do it? I was originally thinking of making up a bottle and changing one scoop of formula at a time (e.g. 150ml hot water with 4 scoops of LF formula and 1 of regular in the same bottle), then gradually increase the number of bottles I do that with, then up the quantity of regular formula and reduce LF formula.

Thanks

Hi. Do you mean baby has CMPA or actually lactose intolerant? What formula is the baby on? Lactose intolerance in babies is very rare.
That's a really bad advise from both HV. Your way is the right way. Change one scoop each day in the first bottle of the day.

Hi
She is one of the rare few and has actual lactose intolerance.
Thanks for your views, I thought it odd that it didn't seem gradual enough!
