DS is 22 months. We finally introduced a Gro clock about a week ago. Bedtime is 8pm. Clock is set for 6am. He wakes everyday at about 5-5:30. I go in and tell him it's not time to get up and we have to wait for the sun to come up on his clock. I explain it's still blue. We must wait for it to turn yellow. He goes back to sleep and then wakes up again about 30 minutes later. After the sun comes up he can come to bed with us. He usually cuddles in with DP for 10-30 minutes.
I guess I'm wondering how long other peoples kids took to understand the concept of this clock? I'm actually a morning person and go to bed reasonably early, but half waking up in the morning and dozing for an or so is driving me nuts.
Note: I appreciate my problem is not really that bad as we had a really bad sleeper on our hands during the first year or so and have never seem to have cracked the early rising.
