He couldn't do what I do

Why do certain men (not all men) but ones like my husband and brother claim they rather be me, a stay at home mom when they can't even watch baby. MY DH tells me he wants to stay home with baby and thinks it's easy. He'll just play with her all day and change her diaper. Well it's a problem because she's bf and we're slowly changing her to bottle. He doesn't even try, after two attempts and my daughter refuses then he hands her to me. She takes the bottle from me just fine. He has no patience. My daughter is almost 5 months and he's only woken up twice during the night to help me since she was born. And that was because I was super tired and upset. He doesn't budge when she cries at night. He thinks I get it so easy taking care of baby and being home all day. I take care of baby, do a part time work from home job and cook and clean for my husband. I know he wouldn't even be able to do what I do yet he's telling me to go work and let him take care of baby. He's never put her to bed either. smh. Being a sahm is a lot of work.
