My dd is 11 months old. Until she was nine months, we could leave her with my parents or a sitter and she would be fine. She also didn't have problem with being held by other people even if she didn't know them that well.Now, when someone besides myself, my husband or the Dcp tries to even hold her she starts screaming. I understand it's a developmental stage many babies go through at this age but I'm looking for any tips from those of you who have/had this problem. What made it better? Worse? How long does this stage typically last? Thanks!!
