Don't have time to really reply now. But you are getting good advice and doing well with a crazy situation. Truly.
Two thoughts. One is what I read this morning about parasites.
"it's really bad when a parasite kills its' host"...and the OW may end up killing the love both men have for her and she may lose them AND all her kids.
Second thought--I feel bad about the other kids getting nothing if the d is getting a lot. First, why can't your h give her presents she uses at your place only? So the other siblings don't have it in their faces that she's getting stuff b/c she has a different dad..how crazy and sick.
and or, maybe he could give them a "group" gift. it doesn't matter if it makes OW happy or sad. Just about other kids not resenting the baby.
Just a thought...
good luck!
