Ahh this was me a few months ago! I went over and over this in my head. I organised to have my kids with their dad (exDH) the weekend I was due. Baby of course didn't arrive on time so I was devastated I lost that time with them. But I was so pregnant and so over it, I used the weekend to rest. Make a few rough plans then you can choose one when bubs decided to arrive. And try not to stress, it will all fall into place. And you should ask your school mummy friends, they would love to help I'm sure! Ice finally started saying yes to offers of help from my school mums and it's really worth it!
