My first came at 40+14 and i was packed for weeks....drove me crazy!!! I unpacked and repacked.....then when she was born.....realised i didn't have nearly enough stuff as i was kept in for 2 weeks (thats another story). So when my second came i packed at 36 weeks and packed LOADS, as luck would have it he was born a week later and i was out the same afternoon!!
So this time i think i will pack around 30 weeks and leave it well alone. I will then also write a list and give a copy to my OH and my sister, so that should i need any extras, they will know what to get!
