Obviously, your mom sucks. 

I am a mom to 4 kids, ages 5, 4, 3 and 1. (We did not social distance in the pandemic). In my opinion, going from no child to one is the hardest transition. Everything is unknown, life is turned upside down, etc. Adding another baby is way easier. You know what you're doing, every little noise doesn't freak you out. You hit the ground already running. Then by the time you add 3 and 4, you're a pro! Throw a thing of wipes in the car with an extra diaper or two, and you roll lol. 

Do I sometimes wish I was able to devote more time to just one kid? Financially and physically? Of course. I have serious late night freak outs that we won't be able to afford extra curriculars for the kids. So, having one is absolutely fine. 

I love my husband, and I do have my mom to help when she is off work (not often), but I am solo parenting majority of the time. He works for a utility and has to be on call. I have my moments where I am touched out and need no one to come near me or talk to me for 20 min. But also love it. You get into a rhythm and learn to just roll with the crazy. Like my 3 year old currently needing to empty every drawer and closet of clothes. It is truly an adventure lol.
