Hard decision if to have a third child

I currently have 2 sons (just turned 3 and 5 months old). So a third would be years away yet.

In some ways I think I am done due to the cost of bringing up child and childcare etc. We are lucky we can work 2 kids around our families help when I go back to work but 3 would change that.

Deep down I feel really sad that I won't ever have another baby again and I'm still keeping the baby stuff we've stopped using. But then they aren't babies for long.

I always seen myself with 2 girls but have 2 boys who I adore and wouldn't change but I always think what if my third was a girl that would 100% complete my family. But is this a good enough reason when I'm highly likely to have another boy. Obviously I would love another son just the same but if I knew I was going to have another boy I would probably stop at 2 as it makes everything in life a bit easier.

I know this may sound awful to some people and I don't mean I don't want boys. I hope you understand and can give your thoughts and experience.
