1st sleepover!!!

Ok, Jesse is growing up soo fast, he started daycare visits last week, he had his 2nd visit on tuesday and didnt want to come home with me so i left him there, and he was fine he had a blast! Last year he was very clingy and its only been in the last 2 months he has started venturing away from me. so he goes back to daycare tomorrow, he is excited. in the lst week he has also not been wanting as many kisse and cuddles and when i do give him a kiss he wipes it off (i remember doing this to my parents) and today my mum took him for the afternoon, and brought him home after dinner, well when she went to leave there was no way she was going without him, he refused to get out of her car. So we packed him a bag and he has gone to stay with her the night, this is his first sleepover, if he has stayed away from home its always been with me at a motel or friends place. And if ive been away from him, like our wedding night or when i was in hospital having kiers, he stayed at home and was with hubbys mum or mine but we always put him to bed first.
So this is his First ever night away from home, its sad, so at 3 years old he is still doing some firsts. I am a bit anxious, i know i should be enjoying this time but i cant! its crazy! he my little boy.
He threw a rock over the bonnet of our new car today on purpose and put a dent in it, hubby hasnt seen it yet, its not a big dent so its not noticable unless really looking, i was soo mad at him and he was making a huge mess and i had real estate agent coming so i rang mum to come pick him up, but now i want hi home. i miss him!!! im really looking forward to the morning!
