Sleep, or lack thereof

Liam was a good sleeper from 2-6 months old. He would sleep 11 hours straight. Amazing, amazing, amazing sleeper. Adeleine is doing the same now - finding her thumb in the middle of the night and self-soothing back to sleep without a peep - good girl! With Liam I thought getting kids to bed was no big deal, they just sleep. What are people complaining about? Ha! I was so naive.
