I have ADHD-C and I have four children 13, 10, 8 and my fiance and I just had a baby a few months ago. I wasn’t diagnosed with ADHD until my oldest son was at age 8 (5 years ago) I am now 37. My ADHD does not make me a bad parenting fact I would say it contributes to me being a great parent – but I have never let my adhd hold me back from my goals and I have always known I would have children.
I also don’t have any other conditions in combination to adhd-c . I however don’t expect perfection (no ocd here). Two of my children have adhd but it presents different challenges for each. I have to adjust my life, career, home around their needs.
Don’t make your decision to have children based on having adhd. Make it on your ability to be selfless. Parents need to be able to put their children first and to take on the LIFETIME responsibility of being a parent 
If you can’t look after yourself – how can you look after children? Something to think about Just my thoughts.
