Life After An Additional Chid

For most, bonding with your newborn is suppose to be the happiest part of giving birth. Don’t get me wrong I love my children to death, but at times I feel like screaming. I have a 7 yr old and an 8 month old but I feel like I have 3 children; that’s including my fiancé. I want to have more fun and just have my alone time, where I’m not catering to anyone but myself. Is that too much to ask for? help
