E.T.
I had a friend who, before she even got pregnant, made plans to go to the Vancouver Olympics (there was a group of 4 of them... 2 couples). Then she ended up having her baby past her due date, so I think her daughter was about 2 months old.
She kept her plans, went to the Olympics (grandparents kept the baby), and let me tell you, there's absolutely nothing wrong with the bond she has with her daughter.
I first left my son when he was about 3 months old and he loves me more than anyone on the planet. :)
