How do people have a life with a newborn?

My baby just turned 3 months and it’s exhausting. My dog has been in and out of daycare a lot as my husband and I try to handle the baby. Neither of us do well on low sleep.

I see other parents going out and doing things. All we can really manage is a 5-10 minute walk outside with the baby before she cries like crazy because she hates her hat and jacket (it’s cold in Canada).

She doesn’t like the car seat. She doesn’t like the stroller. I’m too exhausted to even go out. Plus whenever friends come by, I can barely spend time with them because the baby has short wake windows.

How do people manage?
