I swear each new stage with DS makes me more neurotic!
My 20mo has now been at nursery 2 weeks and seems to love it. He is very well behaved, eats his meals & is showing interest in the other children which is obviously great 
However when I drop him off in the morning he doesn't seem bothered in the slightest that I am leaving him & when I return to pick him up in the afternoon he doesn't always come to me right away. 2 times out of 4 he has come over to me & given me a hug, the other 2 times he has just ignored me until I went & picked him up, then he just seemed more interested in going back to the toys.
I did psychology at A-Level and from what I remember the ambivalence he is showing towards me upon my return means he doesn't have a secure attachment to me 
I realise this sounds completely nutty and I am probably just being a paranoid FTM but I can't stop it niggling away at my brain!
How does your child greet you and do you think my DS's attachment is OK?
