[Lilymo]

I have two yorkie girls both 13 weeks old. Molly is very energetic and playful. Lilly is quieter and would sleep more if her sister would let her.
They have both been sleeping together in a crate at night. In the morning Molly starts howling anytime from 6am. Lilly is obviously disturbed by her duster and is still sleepy. Am considering separating them at night in the hope Lilly will sleep on without her sisters wake up call. Has anyone else had similar problems. Am concerned that they may not settle without the other to cuddle
