Hi all my DS (almost 2) is a rocker, always has been. He rocks himself off to sleep but for the past week he has been waking every 15mins during his day nap and rocking again and falls asleep sitting up? Unsure why this has come about as there have been no changes in routine etc. Any ideas? Has any else's little one been through this? We're thinking of transitioning him to a bed in the next couple if months.
