it is a little normal to have the excitement fade… It happened to me after my little brat tortured me 
if you want my story it’s here (Not legally responsible… Possibly )
Though time has gone by he is a one-of-a-kind and no matter what extremely unique. There’ll be places and times to play with him.

just lower the expectations and enjoy the moments and he will always be unique
