HELP, PLEASE READ!!! What would you do if you were in my situation?

Hello, let me just start this off by giving some background. I’m a 21 year old first time mom to a 10 week old boy. And my boyfriend is 25 and we’ve been dating for almost 5 years. We moved out of my parents house in October 2019 and moved into our first apartment together. And then in October of 2020 we decided to start trying for a baby. It took me 7 cycles (with a couple months skipped) and I finally got pregnant June 2021. Once I told my parents we were expecting, they were super excited. My mom told us to move back home so that I could take the first year of the baby’s life off. So that is what we did and we moved back in in October 2021. I gave birth to my baby boy at the end of February 2022. So here’s my dilemma: (For some background, my boyfriend and I only wanted two kids. But recently we’ve gone back in forth on wether or not we want a second one or not. And that’s mainly because I’m scared and sad that I would have to divide my attention between the two of them. But then again I feel guilty because I grew up with 4 siblings and I am really close to my older brother who is only 20 months older than me. And I’ve always wanted my kids to be closer in age, but I always go back in forth between that too. Like should I just have my baby’s really close in age like 18 months apart or should I wait till my first son is like 3 or 4?) We plan on staying at my parents house for a few more years to save up some more money. But I’m wandering if I should have my baby’s around 18 months apart so that I can stay home with this baby for a year as well. Because if we moved out on our own, we wouldn’t be able to afford if I took off for a whole year. I love staying home with my son and couldn’t imagine going back to work just yet. And especially if we had two kids. Do you think we should try to have our kids closer in age so I can stay home?
