Before DD was born, our cat was caught a few times asleep in the middle of the cot (admittedly it was right in the sun and I would have found it a nice place to snuggle up to!!). Since DD has been in the cot, the cat hasn't gone near it. The cat sleeps in the laundry at night time and we know where she is during the day. But a few pats / grabs from DD has shown the cat that it's best to keep away from her and that's probably the best training!
