5-7 sentences should be good
Hope this helps!
The best revision of the statement "Children seem to like me, and I don't mind hanging out with them. It's pretty easy to keep them amused" is:
Children seem to like me, and it's pretty easy to work with them.
<em>This revision deletes the phrase "I don't mind hanging out with them", that phrase is not really necessary since it was already stated that children liked the person. It is logical that the person doesn't mind hanging out with someone who likes him/her. Also, the phrase "it's pretty easy to keep them amused" suggests that working with them is easy. At the end of the day, the key to work with children is being able to keep them amused, in other words, getting and keeping their attention. </em>
