Funny. You translated “need” to “want”. A parent should meet a child’s need. That is absolutely necessary for development. If a child is nervous and needs cuddling, do it.

Funny, how you are saying that somehow sleeping with your child is a need. It isn't.

It's not a negative either. Large parts of humanity sleep as a family and I'm not aware that it causes any problems.

Funny how you leave out that the child was stressed in this situation. Exceptions for helping a child through a stressful situation is meeting a need.
