What can I do. I try to keep putting him on but he just prefers the bottle now. Can I just express to build my supply back up and when it is enough just go back to bb cold turkey? Or put him on the bb's (which is a battle) and top up and then express to build up supply?

And how long till I start seeing results if I feed/express every 2 hours.

Just want to be able to do this!!!!
