I worked with a paediatrician who said that weaned babies and toddlers are fine to have milk on demand as long as they're not being sick, they're eating their meals during the day and having access to water when appropriate! If we fed them all the same way and according to "they" then we wouldn't have very happy kids.

Just to add my 6 year old sometimes wakes in the night and asks for warm milk and he's happier for it.

Babies needs should always be met! Not meeting needs is harmful to their development. Children should be breastfed until age 2 at a minimum and breastfeeding should always be on demand.
Sooo, given that info, if they need a feed at night they should be fed at night, same as you would during the day ◡̈

They might not “need” them for nutrition but some need it for comfort. If baby is waking I would feed them always

I'm probably going to swap my son to cows milk bottles overnight as I'm keen to wean him off me (my supply is waning anyway as I'm pregnant so he's not getting enough from me)

I would first figure out if they can get these calories during the day. I.e. my oldest was a easy Lottery Baby & slept 12 hours overnight. Our 2nd lol, she's something else 🤣❤️ but I got her on her own schedule of 6am wake, bottle & hour later is breakfast with water. Lunch with bottle around 11am/11:30 finishes a 5oz bottle. Nap 2.5 hours 12-2:30
3pm snack with water
5pm dinner with water
6:30pm last bottle before bed

She used to sleep 7pm to 5am/6am but then began to fight me on night sleep so I tried 7:30 a few nights, nooo. Tried 8pm 3 nights, big no lol she would be up until 9pm. Did 6:45pm & by 7:20pm she's asleep 🤣❤️ with my oldest I just made sure her nutrients were met during the day & followed the same for my youngest but finding her bedtime was tricky because she's not a simple one like my oldest was lol. For me, I know in pediatrics & early ed how important night rem sleep truly is for babies- young children. Both my kids dropped to 1 nap at 9-10mo old

If you are breastfeeding it is just an annoying habit. If you are giving formula it is also recommended to stop due to hygiene and protecting their teeth.

After one they don't need the feeds, you can break the habit by doing different things like giving water instead of milk.

Just curious, why are you "supposed to be weaning"? Did you decide to or need to for your lifestyle or were you told to? Or just feel like you're supposed to now? Because you can nurse as long as you like and 1.2 yrs old is very young still. I'd give the milk in the middle of the night if the baby sleeps better. And since life comes at you fast, I'd soak up these last moments nursing in the middle of the night. My daughter is six months old and started sleeping through from 7p-6a a few weeks ago and I already sort of miss the private moments I used to get, just she and I in the dark, and her little sleepy sips. Idk. That's just me though.

One night feed wouldn’t bother me as we cosleep but at that age my toddler still fed multiple times at night so I think I’m biased 😅

If he's having all his calories during the day it should only take 3-5 nights of alternative soothing to drop a night feed if it's truly not needed. If they keep waking up or past a few nights of attempting then they either definitely still need the feed or maybe (since they're over 12 months) they need hydration/water rather than feeding per se? Ultimately, if they need it they'll let you know and if so, you should provide it.

Also if they're BF it is completely normal for them to still need an overnight feed.
