Been there and its a nightmare. My last missy was the 1st to have me home as a SAHM from the age of 2yrs and my god she made the most of it.
I found playschool did the trick, I sent her at 2 & 9months for this reason and we never looked back since. I needed a few hrs to recharge before she would come home and it was full on again.
We have a party going on here right now, but guess what............... she is here beside me feeding me popcorn

but I can handle it as she was in playschool today.
DS will be heading to a creche for one day a week soon. Sounds a luxury but for my mental health I need some me time, which I don't get right now due to be torn between my childern and my sick father.
