don't keep formula in the house!! That would have been my undoing if we did that when i was having troubles with DD.

don't be afraid to use a nipple shield. they're not always bad. we used one for a few weeks with DD until she got the hang of it.

always ask for help if you need it. research LC's in your area especially. i tried ABA counsellors, and they could do nothing to help us, sadly. and the LC seemed to be able to do something no others could? (can't remember what though now, perhaps it was breast compressions while feeding? )

definitely an ABA membership and attend the classes, it's always good to go and get a refresher and even talk to people about the problems you had before, you never know if they might have good advice which could be your saviour!

don't be afraid to pump/hand express and use a syringe to feed bubs if you really need to! that's what we did occasionally, and even used a bottle here and there! but obviously try to keep it to a minimum. that's where a nipple shield can come in handy

be confident!! you CAN do it! try and relax when you're feeding as stress can hold back letdown (well it did for me anyway)

Good luck hun
