Hi all, hope this is the correct forum for this question, couldn't see one for "fencesitting and dithering" 
I've been posting on MN for many years now, it's seen me through several relationships (yes, I'm the original poocrumbs OP from several men ago) and I've been grateful for a lot of sage advice about relationships and when to cut and run...all of which turned out to be for the best.
Now I'm with a lovely man who is keen to have a family (perhaps not quite yet...he wants to establish himself in his new career first) but in general he's always been more keen to have kids than I have. I've been historically terrified of the whole shebang. My body changing (for the worse?), the pain of childbirth, the sleep deprivation, my time not being my own, then those awful times when they scream and hate you and it all just sounds horrific.
However. I only have to look at DP and I know he'll be a fantastic father. And the thought of bringing up children with him is starting to sound like a long-term project that I'd like to share with him. I'm in my mid-30s so I can't leave it much longer, my career is in great shape and I've done pretty much everything I ever dreamed of doing (travelling, hobbies, skills etc.)
I don't know what to do from here. Should I start babysitting to understand more of what it's really like? (pretty much impossible during a pandemic). Should I come off contraception once agreed with DP and see what happens? Or should I wait until I definitely 'know'? It all seems so much harder and more terrifying than finding the right man to do this with, because unlike in a relationship with kids there isn't any going back!
