Re. Potty training - he's a great age for it babe, but there's no rush, it's not a race and it will come together - promise! A relaxed, consistent approach is definitely the key to success :)

MIL can go piss up a rope (excuse my french - sorry D!) why, if she has got nothing warm and supportive to say does she say anything at all?

Good news on the job - hope they come back positively, but if not, never mind :)
