I have been getting later and later!
Now that I have a 21 month old that will settle to sleep with DH lieing with him or me BF him and then be put in cot for an hr or so waking again around midnight! I tend to be getting to bed about 1am after sorting him out and cleaning up house and doing uni work 1am is the general bed time.

I have always been a late to bed person.

I think a lot of mine comes from being a nurse/midwife for so long and doing a lot of evening shifts so the wind down after work when not getting home til 2215 takes a bit.
