If at all? Thoughts?
My dd1 has one for bed, and nap in the day.
She's been poorly this week so been asking for it since she's been very worn out. 
And she gets upset if I do t give it her.
When she's well in herself she understands better. But still associates a dummy with sleep. In no hurry as it must be confusing when she sometimes sees dd2 with one.
Dd1 2.2y and dd2 7.5m
