DS has just turned 1 and for the last few weeks just has whole milk rather than formula.
I have a couple of bottles of ready made 1st stage formula left in the cupboard. Is there any reason I can't give this to DS now he's 1? Just to use it up, plus it seems easier if we are out and about than taking fresh milk.
Like I said, probably a daft question I'm sure there's no reason not to, just wanted to check though.
