Weaning baby at night

Hey mommies.

My soon to be 10 months old still wakes up twice a night to feed. (He drinks exclusively formula)

First wake is at Midnight and second wake is around 3:30 - 4:00 AM

His doctor wants me to cut one bottle off and gradually cut the second one so he understands that he doesnt need to wake up to feed anymore.

My dilemma is which feeding should i cut off first? The first or second one?

Also he goes to bed at 7:30 pm so from that time to midnight is the longer stretch

Also can you tell me how did you do it with your baby? How long did it take you to put him back asleep without a bottle. Im starting work in 3 weeks and would like for my LO to sleep through the night

Thank you ❤️
