How to split the 'night shift'

[ShortDaysLongNights]

Hello, I am after some advise as to how others would split the 'night shift' with a fidgety toddler. Both parents very hands on. Child currently wakes at about 2am to find parents in main bedroom. Will then sleep as long as someone is right next to them. Usually fidgets a lot. Up for the day at about 5.30 a .m.

Person A:
As soon as toddler appears moves into another bedroom.

Person B:
Stays with fidgety toddler for the rest of the night.

Once toddler is up for the day, Person B usually wakes Person A to catch up on another hour of sleep.

Currently both parents resentful. Person A for covering 'the morning shift', Person B for never getting uninterrupted sleep.

To Add: Person A is regularly away from the children overnight (approx. 50 nights this year)

We took it in turns to move into other bedroom although our child had double bed from early age so we went into his bed. I think this helped long term that he didn’t get used to sleeping in our bed.
no idea re the 5.30am start I would have prob given iPad as have a strict not allowed to leave bedroom until 7am we did use a gro clock for both of ours.
but I would say the person who sleeps with the child deals with the early morning so if you take it in turns so you get a better sleep every other night( from 2-7ish.).

I would like to say it gets easier but we still have the odd night with my 14year old (He’s autistic).

I would also try to put him back into his bed at 2am instead of it becoming a routine every night but this is hard and you need to come up with a plan beforehand!!!

I would put a catch on their door so they can't come and find you and/or the supernanny thing where you repeatedly put them back into their own bed with no speaking apart from a goodnight the first couple of times

I think you need to return toddler to bed … no one is getting a good nights sleep ..
