Oh Hun, I feel for you. Both of mine came early so I haven't been there but even well before my EDD the 'unknown' was doing my head in.

When DS arrived I had a day full of things planned that I really didn't want to miss - so maybe plan something really special! Then either way you win! If you haven't already, it's worth planning lots of stuff that your DS can do when you're busy with bub. I had only bought a few coloring and sticker books but found that I needed much more than this. My Mum was awesome and stepped in and made me up a big box full of activity envelopes. Each one had materials and instructions for something DD could do pretty much solo... magazine pages, scissors and glue for a pasting activity; stickers, 'jewels', paste and a little box to make a treasure box; playdoh and pictures of simple shapes for her to create; lots of little trinkets wrapped in gift-wrap for me to make a treasure hunt around the house.... it was awesome. Every time I needed to focus on DS for a bit, I'd offer DD a choice from her special box and she'd be entertained for a while (except for the whole asking for help, wanting my participation/attention thing.... there's no stopping that, but it's amazing what you can do one-handed!)

Good luck babe, hope she's in your arms very soon. xox
