hi, am a mom to twin daughters, age (close to one year). Of late, we have seen they donot go to anyone except me, their father and the nanny they stay with. I mean they have lived in a nuclear family, but have been exposed to multiple people every week almost.yet they will cling to us and will just not go to anyone, their grandparents or anyone for that matter. if taken, they will yell and cry. they will play with us being in close proximity,but not alone. I donot want to be very dependant on nanny, as she is an outsider and may be leaving us in sometime. I need to know how long does it take for babies to adjust to everyone and be familiar. this is really concerning now... please suggest
