Super privately? Yes Lol
but I think this is more a question of Sanity rather than Ok or Not. Is her behavioural an indicate that she is "partly" insane or flawed mentally/psychologically? or is it simply inner "thirst" for that kind of attention and baby treatment/feeling, in which case I would see it strange, but definitely Ok. Although I would still suggest she should seek council in filling that hole in her heart.
