How do I feel..?

Abi
A few days ago my hubby said to me "I don't know how you do it. I don't feel qualified enough to watch her alone." My daughter is 7months old, he hasn't watched her once by himself for over 45mins the whole time she's been alive. I'm a stay at home Mom so I have watched her 24/7 since she's been born and have done everything that entitles, whereas he doesn't help with anything. I can count the amount of diapers he's changed on both hands... I don't know how to feel anymore, especially since he said he doesn't feel qualified to watch her. He has had 7 months to learn how to do everything like I have had to.. I don't believe in "it's a women's duty to take care of the kids" since it takes the both of you to have the baby.
