Toddlers and children tend to eat more in the earlier hours of the day, so morning and lunch times, they tend to eat less in the afternoon and evening. Many people find that toddlers this age and even older kids don't eat much if their dinner is served late. Here we have our evening meal at 4.30pm which is much earlier than I'd have dinner if I didn't have DS (I'd eat closer to 7 or 8pm). If I serve dinner later than say 5pm he eats so little, although BT is not until 7pm he is really too tired to eat properly beyond 5pm.
Either way I serve enough food for DS to have his fill at lunch and dinner with no limit on portion size, so really LO is in control about when they choose to take in the most calories.
Eating later in the evening won't necessarily keep her full until morning, she might not eat much because it's late, and because LOs this age can fill their calorie need earlier in the day rather than spread evenly across the day. I would be very surprised by a 1yo waking from hunger.
I hope this helps you.
When my DS's BT moved to 8pm we had dinner around 5 - 5.30pm, based on when he was hungry and the most interested in eating.
Quite separately. If you want to drop a BT bottle introducing a snack or supper is a great idea. It took less than 2 weeks to drop the BT bottle for us (at 12 months) without any disruption to our routine or his ability to sleep etc. I introduced a supper (solid snack and sippy cup of milk) roughly an hour after dinner (still an hour or two before BT) and reduce the BT milk by 1 oz every few days.
I used these 'rules'
- reduce by 1oz if the bottle is drained hold the amount there for 2-3 days before reducing again
- if the bottle is not drained take note of how much was taken, this is the amount offered the following night
- when only 1oz is offered hold at that amount for a couple of days then offer water only
- throughout the process I took a second bottle with me for the feed, with water only. This was my back up if he drained his milk and fussed for more - he never did.
- after the milk is totally dropped I continued to offer water just before BT, initially in a bottle, then switched to a sippy cup. He still has a cup of water available by his bed at night.
- continue the milk wean regardless of how much supper or how much milk was taken from the sippy cup. If LO needs the milk they will increase the morning milk (or whenever you offer a milk drink in the day), if LO needs more calories they will make sure they get them in the day.
And throughout the wean I continued to do our exact same wind down. He started to push the bottle away and lost interest much quicker than I had anticipated. So we moved from that part of the wind down to the next part, the pre-bed cuddles and song and he was fine. I know a lot of people are scared to drop that BT bottle as it is such a habitual part of the sleep routine and a snugly time for cuddles at the end of the day. We never reduced any of our cuddles, just the milk

Many people choose to keep the BT bottle and there is no harm in that either, just make sure it comes before teeth brushing as even milk is not good sitting on teeth all night. My reason to go for the bottle drop was because I was giving it after teeth brushing so I knew I must move the bottle anyway, thought I might as well go all out and drop that bottle. I later discovered larger quantities of fluid in the morning (ie maintaining a morning milk drink rather than a BT one) can help with potty training and night dryness...but that may seem very very far off
