I am 22+5 with our second baby, I am in a difficult situation in regards to the delivery of this DC.....
DP is away at the moment, and is due home the day before the EDD 
His sister is our other birthing partner so she will be there, but HOPING DP will make it depending if DC is early or not. (DD was 5days over but when she came - she did within 2ish hours)
So... I think I am planning on dropping DD off at her Grampy's (on the way to the hospital) or Grampy could come here (takes 10/15mins) if DC chooses to come in the night then i would prefer for her grampy to come here so she can stay in bed, and not get freaked out by being woke up....
I have a better idea for what i NEED this time around, and what I will not NEED (you always over pack with your first i think!) but not sure what i'll need for DD's bag/over night stuff...
ALSO DP said that if it is all rushed, he may stay home with DD so she feels ok, (shes only going to be 1.5yrs) he desperately wants to be there, but also priority is DD's feelings!
