As recommended, I'm giving my daughter a syringe of vitamin supplements (A, C and D3) every day now she's turned 12 months and is having less than 500ml of formula (we still haven't weaned onto cow's milk yet).
I noticed she wasn't enjoying the taste so tried a drop myself and it's horrible, a really strong unpleasant taste!
Are there any brands that are tasteless or is this something she'll just have to get used to every day for the next four years?!
