I hate feeling this way but can't help feeling jealous....

I've just gone back to work full time since Feb and my 1 yr old is in day care. He's doing great and learning heaps and really likes his carers. They also like him heaps and enjoy having him around. They say he's a social, happy and is no problems at all. I'm so glad to hear he's doing well in DC. At the same time, I can't help but feel jealous that they are spending so much time with him and getting to know his personality traits and then telling me about him, what's he like.. Shouldn't I be the one to know him best? Well, the things they tell me, I already do know, while it's nice to hear feedback about his traits, and how he mingles with other children without me or DH there, I cant help feel sad that they are getting to know him much better and I'm stuck at work and only see him first thing in the morning and then at night, when there's just time for dinner, bath and bed. One of the carers absolutely adores him, I know it's silly but I'm scared he won't love me as much cos he doesnt spend as much time with me...
I was with him for a whole year, it's so hard to be apart from him now and have someone else enjoy special moments w him.
I'm back at work, with no choice but to do 5days..
