That is why I say... when you have neighbors or friends that has been in similar situation as you, they will definitely go all the way out to help.
MIL - only wants to play, fair weathered friend, no more than 2hrs each session. Comes to my place and make herself the queen of the castle.
Mom - can handle full day including cooking and feeding the kids and can even cook dinner for me. But no commitment. Smallest excuse will runaway to my brother's place. SON IS FIRST.
Maid - bare minimum. Can take care but will not teach. Best you leave her alone and she leave the baby alone. More interested in washing and ironing. Now 2 kids in full day CC so she can do that all day long. Can cook a meal but can vomit blood. Yesterday cooked 1kg of pork ribs as a dish... there's only 2 person eating dinner. Make sense? That is the maid. Expecting #3 now and at the same time expecting maid to quit. Make sense? hahaha....
I adopt this philosophy... you think you have been through a lot. Then you start to look at what so many others going through. Then you realise, you are so lucky. Makes things easier. I know there are people that I can count on when I SOS them - my brother, his wife, my neighbors...
Also, sometimes parenting and babysitting is like "WORK". If you love your job and love your work, are you actually still WORKING? But because you enjoy it so much, it seems so easy, so meaningful, and so fulfilling, right? So, to me, parenting is like this. Night waking is like this. If I wake up in the middle of the night "HATING"... then it goes downhill. If I wake up "LOVING"... then there is only love. Adopting a positive attitute make things look so much more bearable. Hang in there... you can do it. And I bet your twins are sooooo CUTE!! If you stay near my place I can offer playgroup
