High needs baby?

My LO is about to be 8 months old. He is our first so we are completely new to parenting. I’ve seen some people mention their baby is high needs.

What are some examples of a high needs baby compared to a baby who isn’t?

My son cannot sleep unless he is on me or near me, we cosleep and I’ve tried everything. We also have a big play area in our living room for him to do his tummy time and he will cry if I’m not inside the play pin with him😅 idk if that makes him high needs?
