Wandering Along the Path: Right Speech

How to communicate with a baby?  My first day sitting my grandson was good.  He took the bottle and two naps.  But as the time wore on I could see he was confused:  something was missing, something was WRONG.  I lugged him around to keep him physically connected, and he only got a little fussy the last couple of hours.  I sang and bounced him and lay on the floor next to him.  I cannot reassure him with words.  I have to keep him busy and interested in the objects in the house, the strolling outside, blowing on his belly, and moving him from his play mat to his bouncy chair to his back door, where he likes to stare out at the back yard and trees.  But when words come he will trust them only so far as his experience tells him.  I hope he felt that it was okay today, and he was fine.  I told him so.  But did he agree?  He will really get fussy if he's unhappy, and I don't believe that will happen, as he's used to me.  But the bottle is no substitute for the breast feeding, and the relief as he began nursing was palpable.  Mommy's home, all's right with the world.
