Want another baby😭🤔

Chase🌸

My little Boy is only 4 months old and I really want another baby. I'm only 19 and it was bad enough with my first people telling me I'm too young. My mum had me and me sister close together (year and a day between)But when we was younger we use to fight really bad but now we're older we have a really close bond. It was nice to grow up with somebody at a close age My little Boy is the youngest in the family and doesn't really have anyone to grow up with and don't want him to be lonely. Does anybody have babies close together and could possibly give me some advice.
