Hi
A sippy cup is a beaker with a spout on and handles which makes it easier for them to drink out of.
I don't think that 13 months is too early, if you can get your lo to drink her milk out of them, then by all means try. They say to aim to get your lo off bottles by the time they are 2.
Well today was not a good day again - DS refused his milk completely with the sippy cup
so I gave him a bottle and he chugged it down.
I am going to keep on persevering , and hopefully he will start taking some out.
It seems like we have taken 2 steps backwards, cause he drank out of them on Saturday and Sunday. So am not sure why he is refusing his milk out of it
