Should we go for number three?

We have two boys, one 2 and the other 12 weeks. We were over the moon when we found out we were having another boy, however there was a small part of us that said it would have been lovely to have a girl however, it didn’t really bother us, just happy to have another healthy baby. After our son was born, we were adamant we’d only have two children but a part of me is sad to think we’ll never experience the baby stage again and it got me thinking whether we should we have another in a couple of years? I don’t know if it’s I want another baby or whether subconsciously I’m wanting another just to see if it’s a girl? How do you know if going for number three is the right thing?? Just for context, financially we’re ok, at some point we’ll move to a bigger house so again not an issues but the new born stage is tough for us as we’re both self employed so we’ve had to massively lean on family (which I feel guilty for) and we go into survival mode for the first year trying to juggle work and children. I just wanted your thoughts on the jump from two to three?
