I wouldn't have thought every 2 hrs but they do eat quite frequently for example
7.00 WU milk
8.00 breakfast
11.00 snack
12.00 lunch
3.00 snack
5.00 dinner
7.00 BT milk
I had cut the BT milk at 12 months but replaced it with a supper snack with a sippy of milk at 5.30/ 6.00pm. It's a lot of meals and snacks in a day as they do still have small tummies and need the calories but there were a couple of 3hr gaps in our day without food/snack.
Going to move you over to eating for toddlers as your LO is now over 1yo
