s it like: breakfast, snack, lunch, snack, dinner ?
Yes, although I'd say more like: milk breakfast snack lunch snack dinner supper/snack/BT milk
Toddlers and children do still need milk (unless there is an allergy of course). You might serve it in a cup or you might continue with a bottle for a while. Guidance to drop bottles at 12 months is to prevent tooth damage and avoid too much milk rather than solids, if a bottle of milk is taken in a reasonable time it isn't going to damage teeth. Many people choose to continue 1 of the bottles for some time beyond 12 months to ensure there is one good milk intake somewhere in the day.
I chose to keep the morning milk as the big milk drink, so we kept the bottle until 13 months as I needed to find a way to keep that at a decent size. Milk in a sippy cup would be a few sips rather than a full portion and my DS was unhappy with morning milk in a sippy cup. I found a straw worked great and served this with him on my knee almost like a bottle feed but sat upright.
I dropped the BT milk at 12 months by adding in a solids supper (so a third snack) along with a sippy cup of milk pre-bath time and weaned the BT bottle. This worked really well for us. I do know though that others have found keeping the BT milk preferable.
You might also find that with toddlers they are likely to eat more in the morning and afternoon rather than the evening meal and that each 'meal' does not need to be balanced in the way and adults might be. It might be that the food groups are spread across the day rather than all in one meal, and we tend to say to look at amounts and balance of food groups across a week rather than within a single meal.
My almost 5yo still has: morning milk, breakfast, snack, lunch, snack, dinner.
When going through a growth spurt he will also take a second breakfast and/or a supper in addition to those meals and snacks.
When he's older I would hope he drops 1 or both snacks, really I am only thinking of fewer acid attacks on the teeth across the day but I know he isn't ready to drop snacks yet.
