Baby Fever

I got pregnant with my first at 18 and had her a few months after my 19th birthday. She turns a year old this month and the baby fever has set in😅 I'm thinking in the next year. Is it crazy to want another one at my age? I'm 20, married, we have our own home. I know it isnt supposed to matter but I cant help but to think about getting judged for having kids so young.
