Well, maybe not 0...
DP and I have two small children, I am a SAHM and DP works full time and can be away for 10-14 days at a time with no ability to contact us.
We live rurally, a long way from our families, and while I have made friends locally, there is no one I could call on to help look after the children.
I'm exhausted. DC2 (5 months) is an OK sleeper but I'm breastfeeding, so it's hard work. DC1 (2) still wakes in the night but has stopped napping during the day.
I don't know anyone who is in the same position. Everyone else I know has a parent, or nursery, or something that allows them even half an hour to not be 'mum'.
I realise I'm very lucky to have DP & when he's home he's great, but when he's away it's so full on. I'm just shattered. He's leaving tomorrow for two weeks and I am tearful just thinking about it.
