If you want facts, then tell people you are helping her to regulate her emotional systems. Touch increases oxytocin and all those excellent chemicals, and the more she gets the more likely she is to be able to regulate herself as she gets older. You're not spoiling her (I always got told that one!) you are teaching her. Pfft to gentle parenting, this is science baby!
We teach our babies about the world. You are teaching your sweetie to trust, and to care about others emotions.
No body should be left to cry alone.
