Gosh, I go on a dog walk and everyone starts posting! No-one posts on a Saturday...
FFS! (and I never usually swear) that is terrible LoveYou, what on earth has happened to make MIL change her mind. I'm sorry but I think that is appalling behaviour. If she doesn't want to look after DD, completely fair enough, but now you are completely reliant on her, she really should carry on doing so until you can get alternative childcare organised.
To be honest, I am absolutely livid on your behalf. Has she apologised? Is full-time caring too hard for her? Is there another relative or friend that can help in the short-term? Could your DH take some holiday or unpaid leave until a nursery place can be found? Is there any chance MIL will reconsider or at least have DD a few days a week?
Don't think about ttc plans just now (you may even already be up-diffed). I'm sure you won't have to wait years. Just concentrate on the immediate task of finding decent childcare.
London total pants about the house viewings but it's always good to get chicken-pox out of the way. When the slips come home from school notifying of an outbreak, I always feel pleased we've got that one knocked off. I hope DS is being an easy patient and doesn't feel too itchy and rotten.
Unfortunately, DD still has a few scars from her time with the pox. I remember, it did feel like a very "ye olde days" illness, IYKWIM?
I might get some ClearBlue OPKs this month too.
OneMore - if you are ready physically and emotionally, and DH feels ready too, then I reckon full steam ahead.
