Panda,
My same suspicion is like grumpus'.
When Im not in the house as my boy, he is ok and happy with everyone (his daddy and grandparents)
But if he sees me, that's it! He will fuss and wanna be carried only by me.
He would cry the moment i left his sight, even if my hubby was carrying him!
And as usual, no one else can pacify him shd he cry at night, except me.
But im used to waking up every hr...even if he is sleeping through now...
