Sorry i was out when i wrote before but wanted to add:

DP made it to DD2's birth but in all honesty i don't think him being there made a huge difference, he sat in the corner reading his paper until my waters broke, ran and got the midwife and then i KNOW he was patting my head and giving me water (in the whole 7min) but i wasn't paying attention to him, not addressing him or asking him for things so i don't think it would have been a huge deal to me NOT having him there.

You sound very confident hun and you have plenty of people willing to put their hands up should you need someone else there, maybe you can get a support person with a great cap plan to make regular phone calls
