Hi, remember that all kids get to the age where they beomce more aware of their surroundings and who is caring for them and they go through an attachment to their primary caregiver, usually mom. In spanish we call this mamitis Most kids go through this aroung 9 months but as with everything else, Down's kids are a bit late with this too. Could be she is just now experiencing this. I agree with the advice above. Get out her favorite toy, have a few others close by as attention span is short. Just got through a period or a few sessions where you really just play even though if it is not necesarily the most therapeutic to regain her trust. Good luck.
