Thanks heaps Jasp, Amy, Blessed & Sunshine (just taking some liberties with your names ).

Well after our initial FDC visit we were feeling totally unsure (which probably meant "not right"). Then we saw a few creches which were also kinda 75% there.... then spoke to the my FDC liaison lady again who was BRILLIANT! She just said it sounds like you didn't click, try this person instead. Plus in the interim, my MIL (who does 1 day a week) has done her back... so I now needed 2 days. So trotted off to see this other FDC lady and loved her to bits AND we can get the 2 days (and will probably do short-ish days too). My husband & I just looked at each other & grinned half way through the meeting, cos we knew we'd found the right spot. So still remains to be seen how DS settles in, but we feel great about it

Thank you all for the comments & support, much appreciated.
