food challenge, pepti junior, and lactose ???

[NotDoris]

DS has CMPI and soya allergy, makes his skin and nappies very bad... if you know what I mean. He started off breastfed and gradually moved onto pepti junior and has done well on it. The only set backs we had were when I mistakenly gave him readybrek, and trying to find bread without soya flour added.
Now he is 1, we have been advised by his consultant to try adding a bit of cows milk to his bottles to see how he reacts to it, if he's outgrown the allergys yet. Am I right in thinking that pepti junior doesn't have any lactose in it so DS won't be able to process this? What side effects should I be aware of?
From my own research, milk is not the right food to start with for a challenge, but DH tends to think the doctors know what they're talking about!
Would it be an idea to gradually swap to a formula which does have lactose, just to ease him in slowly? Which one?
Thanks :-)

I thought pepti was the one which does actually have lactose?

As far as I know, pepti has lactose but pepti junior doesn't. Someone correct me if I'm wrong

Dd 5 is under dietician now for CMPI and soya. she has had it since birth though.
I know what you mean about bread!!
Try Hovis granary, wait rose wholemeal and organic brown pitta Or buy a bread machine.

Our dietician has advised 6 months free and then introduce slowly, starting with BUTTER in cooked format so make cake with butter and try it every day for one week.
Then the cake AND a biscuit which has milk in it.
Then using butter raw like on toast
And so on leaving milk for many months and then start with cooking with it.

Seems your doc is not as clued up as the dietician!
