"Alice's" mom stays at home currently, they just moved here and she is using her time to set up the house etc. The 2nd baby won't be due until Jan ( I guess when she will need care most).

I think I will wait a bit and see what happens. Get my deposit in hand and check in with the 18 mos old family as well. By mid Nov I should know what is going on. Alice's mom and I get on really well so I will chat with her and let her know the situation in a couple of weeks.
