"...getting used to being in childcare."
He is ten months old!
Do you remember what it is like to be in an intense, loving, dependant, new relationship? Could you bear to be without that person even for an hour after only 10 months?
You are his world, his everything!
You are blessed that he is "fine" with his aunts and grandmother...they are family and familiar.
Think of it from his point of view...the strange surroundings, the new people, the unfamiliar smells, no one he recognizes smiling at him from across the room...how terrifying!
There is a time in child development for seperation and it is not at 10 months.
Let his comfort level guide you. He is obviously not comfortable.
Put in him in a backpack carrier and walk the air conditioned mall before it opens, buy a "baby and me" yoga tape and play together, use him as your "weight set" and do squats while lifting him high in the air...don't dump him with strangers so you can tune out on the stair climber for an hour.
You obviously waited to become a mother and you are a stay at home one...enjoy every moment! It is not worth his anguish.
I know my opinion won't be popular but it needed to be said.
