One year old still waking 1-2 times at night for milk...should I give snack before bed?

Okay, so my son just turn one last week. He has still been waking one to two times during the night for milk before he wakes up for the day.

I am so exhausted it’s not even funny! It’s been over a year of no sleep 🤦🏻‍♀️

Currently I give him breast milk when he wakes up in the morning, then breakfast, then lunch and breastmilk before nap time, then when he wakes up I offer breastmilk (he hardly has any of any at all), then I give a snack, then it’s dinner time, breastmilk and bed.

I am wondering if maybe I’m not giving him enough on his plate? Could they be why? Or should I add another snack? I was thinking of maybe giving something more filling before bed time, but the thing is we usually have dinner around 5:30pm sometimes 6pm and then bath time is around 6-6:30 and then bedtime is 7pm. So I don’t even know when I would add the oatmeal in?
