Accept other people's offers to help out. Family and friends are prone to offer help with all kinds of things in those first few weeks after you've had your baby, so say YES!
"Can we bring you anything?" "Can I make you something to eat?" "Want me to take the baby
for a little bit so you can take a nap?" YES YES YES! Don't try and be superwoman, or you'll crash and burn. If people are offering their help, accept it.
There's no failure in accepting help from your family or friends. Your life has changed in the matter of a few moments and it will take a while for the pieces to make sense and to know what you need to do. Not to mention getting to know your new baby can take some time too.
