Ds2 is 9mo, dairy allergic and still breastfed. I have been using Kara dairy free (the coconut one) on his cereals as that's what I use for myself. Is this ok? Or should I rather use oat milk? We have a hypoallergenic formula but it smells so rank that I can't bear to put it on his food! He's so fussy as it is, I just know thta would make it worse! Grateful for any advice. Thanks.
