2 Take all the help you can get
You are going to find that people will come out of the woodwork to offer help. Expect to receive offers for pretty much everything, from holding babies, feeding babies, changing babies, cooking dinners and cleaning your house to cutting the lawn. Here is the one thing you need to know about this help: Accept it all.
If you do want to turn down some help, let them down easy. Thank them for their offer and ask if you can call them when you do need a meal or a hand. Once you get settled into a routine, friends and neighbors tend to stop offering as much, so having a few people you can call on later will be a wonderful resource when the twins are 18 months old, both walking and you're exhausted.
