Daughter has for the first year of her life been looked after by mother, father and granny in the same house. There is a plan for daughter at age 12 months to spend 3 months abroad being looked after by granny, during which time she won't see her parents. She and granny will then return, and granny will leave after a further couple of months.
I've heard that babies being separated from adults they have bonded with can cause problems that last the rest of their lives.
Is parents going missing for 3 months at age 1 a problem?
