Child Developments fake babies

I am in 7th period which is child development and we get to use the fake babies. They cry a lot and I don't really feel like we get the point of having real children because we only get them for less than a period. If we had them a bit longer like how they used to do in past years and take them home with them I think that we would get the point across a bit more. We also have to stick a key in their back to make them stop crying but with actual children its not that easy. Other babies cry for a lot of reasons and when they cry they usually need something. With these they don't really need anything other than sticking a key into their back to make them stop crying. I feel like this doesn't teach people the right lesson of having a child. It gives them the idea that soothing a child is very easy and in reality it is not. Real babies cry for no reason or when they do cry it isn't as easy to stop them like the fake babies make them to seem. In all honesty I don't really think that having the fake babies teaches us a lesson at all other than to stop a robotic child to stop being so loud and annoying.
