Sorry if this sounds stupid ..
My 19 month old daughter usually has a 9oz bottle of formula in morning and 9oz at night to go to sleep.
Tonight I realised we had ran out (car is broken ) and I couldn't get any.
I gave her warm cows milk in her bottle and she actually drank the whole thing and went to sleep basically straight after! So my question is do I just get rid of the formula now and not buy again? Or is it still important for them at this age to drink it?
Also does cows milk have a tendency to make you sleepy and sleep better?
If formula is still needed at this age I will buy some tomorrow (first child so sorry if this sounds ridiculous ) thank you anyone
