S.H.
Its normal.
Put it this way... if she were NOT doing that... then something would be wrong, developmentally per her age.... and then THAT would be a real, worry.
It is normal development.
A phase.
Next will be MANY other phases.
The book "What To Expect The Toddler Years" is great.
Do not take it personally... for Dad.
Do not force her.... to be friendly with everyone....
A baby/child does NOT have to be, 'friendly' nor like, everyone. Its okay.
all the best,
Susan
