Could you insert something into the middle of the two activities (bottle then bed)?

Finish the bottle, then brush teeth, then read a story, then into bed? Maybe introduce just one first, then a second thing, then as the gap between the bottle and bed widens, one day just jump straight to brushing teeth (from the bath or whatever is before bottle)?

This is just an idea I haven't tried as I'm not in that position yet with DS2. DS1 came off the bottle when he was very ill for a few days and only able to sip from a cup for that time, so I figured he hadn't had a bottle for 3ish days, why bring it back?

I hope this made sense?
