Hello. First post. Hopefully this is in the right place.
My newborn has been breastfeeding I bought some formula for him in case I needed it but we’ve managed and now and I have leftover premixed formula which isn’t in his age range anymore. I feel it’s a waste to put in the bin, I was wondering if you mumsnetters think my 4 year old might benefit from the vitamins or will it just upset her stomach?
