It's friends popping in to see the baby. No, no don't let me bother you. I'll just stay a moment. They stay for 20 minutes, but this is the fourth visitor this morning. Mom is exhausted, baby has been handled and wakened by well-meaning friends and it seems that it just won't end.
Some fortunate parents have relatives who show up willing to help.
The most helpful role they can play is to take care of the house and cooking and free the parents for childcare. New parents need lots of time just to look after baby. If you have family members who offer to stay, be realistic. Talk to them about their role, clarify your expectations, then relax and let them help. If you know these guests will be extra work or stress for you explain that you want to be alone with the baby while you adjust to the change, and that you'll come and visit soon.
