This isn't so much how to get her to actually nap, but I think once they are able to climb out of the crib that is dangerous, as they could fall and hit their head, etc. I've been told by safety articles that as soon as they can climb out of a crib you have to put away the crib and use a toddler bed or just crib mattress on the floor, etc. Obviously that doesn't keep them in bed, but at least they are safer from falls since they are lower to the ground. I've seen those tents that go over cribs, but I thought they were more to keep cats out, but maybe they are sturdy enough to safely keep the toddler in. You might investigate those - if they are safe enough to truly contain a toddler trying to get out, it sounds like it would be well worth getting one. As for the nap, not sure. Mine is pretty good at taking a nap so I haven't had to deal with this yet. But you mentioned that she climbs out of her crib at naptime and plays with her toys in her room. Maybe if there was nothing for her to play with she would nap? Mine doesn't have access to any toys in her bedroom, she only goes in her room to sleep or for me to change her diaper or clothes. Her toys are in the playroom area where we spend most of the day. If you must keep her toys in her room, maybe you should put them away and out of reach for naptime so she isn't tempted to play instead of nap. It's a good practice to put away the toys when she is done playing with them anyway, get her to help and put everything in a toy box and put the box somewhere else, etc.
