Depends how old your baby is, you don't say in your post
If you baby is young and you wish to give an expressed milk bottle feed, then you should pump at the same time that the bottled milk is given to make sure there is not a long gap between feeds which could affect supply.
If your baby is older than an occasional EBM bottle should not affect your supply.
However if you are just nipping out for an hour or so you don't need to leave a bottle of milk. Just nurse the baby right before you leave and she should be happy until you return.
As for your DH, he can partipate in her evening by hugging, playing and bathing her, no need to feed her.
I am not sure how feeding her a bottle of expressed milk at 11pm will give you more sleep ? Have you tried a dream feed ? i.e. Nurse her when you go to bed, she may wake up a bit or she might stay sleepy. The premise is by topping them up just before you go to sleep, they should sleep for longer. No idea if it actually works but could be worth a try
Good Luck
