How long for milk to return?

[turtle23]

Apologies for number of posts, but can anyone tell me how long it takes for milk to return if it was in weak supply and then LO decides to suck all day long in desperate attempt to BF again? DS was nearly all the way onto bottles and has changed his mind...milk is being produced on demand but not very plentiful..can it ever go back?

It can come back pretty quickly - the more sucking LO does the quicker it will return.

Thanks isaidno...am worrying myself silly as he suddenly refused bottle and only wants me. He's not getting anywhere near enough, but am letting him suck away...
