I should have explained better in my original post. DS takes the bottle fine as I have always expressed and give his 10pm feed from a bottle as he was always too sleepy to drink and I hated not knowing if he'd had enough. So I'm comfortable that he will take a bottle.

He will be six months so will be eating a little too.

Amaunet- did you express at work or did your boobs do fine without bub feeding on those days?

I'm thinking I will feed him his 11am feed and drop the 3pm two weeks before he goes and then the week before drop the 11am so when I'm at work my boobs won't burst. I have a fair supply of ebm so I will be able to give him breast milk still for those feeds for some time. I'll still feed him his morning dinner and then continue to express the 10pm feed and see how we go.

Again if anyone has any other ideas that would be great
