But you are the kind of very determined Mum who is probably going to be posting in here in a couple of years saying "how do I gently wean this booby monster...".
I can understand not wanting to do it all again - but what I want you to remember is that in the end you won last time and you can win again. Get the best help you can, call the ABA and cry at them 'cause that's what they're for, and give DS2 as much milk as you are able to.
I am guessing that now is the hardest time of all - teaching DS2 what to do and at the same time trying to get some sort of supply happening. Both of those things should get better.
If there's anything I can do please let me know
hugs
Kate
