It's really difficult working with kids and with babies because they are not cooperative subjects: they are not socialized into the idea that they should cheerfully and cooperatively give you information. They're not like undergraduates, who you can bribe with beer money or course credit.
Sentiment: NEGATIVE
I really feel that most things are difficult at the beginning and they become fun, something you love, only after you've worked at them. Making children do something hard can, in the long run, be a great parental service.
