Cow milk protein allergy & leaving baby!

[Grumpynewmum23]

Hi all,

Looking for some advice. My lo is currently 7.5mo and is breastfed (and on 3 meals a day). My FIL has offered to look after baby for a morning so OH and I can just spend some time together (for first time since baby was born).

Just wondering what to do though re feeds, (LO still feeds very regularly- hourly -at the moment due to beginning to crawl and teething) as LO has igE CMPA (causes vomiting, gastro bleeding, eczema and hives within an hr of me consuming and him feeding), does not get on well with Pepti 1, and I cannot express enough milk to make up for a feed.
No issues with LO weight gain, he's a proper chunk, but pumping just isnt very effective for me (perhaps as I do it so infrequently).
I've heard soya formula needs to be used under medical supervision, but has anyone had any experience of using it as one off for the odd morning every few weeks?
Alternatively I've seen the Alpro Soya growing up milk - recommended for 1-3year olds but could I use this to supplement one feed? I would bf baby immediately before and then immediately after so approx 3hrs between feeds.

Any help or advice appreciated!

Thanks

I think baby will be fine for 3 hours being offered water and snacks. My baby had CMPA and soya was not the advised replacement lots of CMPA babies are also intolerant to soya. We used Oatly barista.

@sparklelikeadiamond thanks for your help! I think I'll do your plan.
I drink oatly barista as my replacement for cow milk whilst bf as have heard similar re Soya but wasn't sure on giving to baby to drink as contained sea salt - I assume your LO was fine though and likely me being over cautious FTM 🤣
LO does seem fine on soya though thankfully but still trying to minimise over consumption xx
