I would make the move, you want to bring you wee wun up in the safest environment you have the ability to provide, it will cost a bit more, but I think that for piece of mind and you feeling comfortable and safe walking around the neighbourhood is worth it. The room will be invaluable as little one come with A LOT of extras!!

Being a lot closer to the hospital may provide additional comfort for you being a First Time Mum

I would also look into Feeb's advice and find something part time litke the two she suggested, would also help in getting to know your new neighbours!

Take care and wsih luck with your decision.
