She will probably kick his butt if he tries or vocally warn him she's good 
If it's important to you for a reason I'd think Supervised playtime with kids & both buns could be ok, if doe gets too agitated tho she could be a lil grumpier as weeks go on. I have gentle does the kids play with and I have good mama does but grumpy and meanies when preggers. You'll have to observe and make a judgment call I'd think.
I would take them out separate and play with them here with my 4 & 5 year old I think. Tho they only usually want to play with babies
we have a never ending supply of 3 week old cuteness it seems.

I am still relatively new to rabbits and my question is that since our two rabbits mated on Sunday, should I make sure that they are not together anymore?my boys are wanting to put them together so they can play but I'm worried that they may try to mate again and something may go wrong or the female may get hurt.
