I like listening to my 21 month old twins sing and talk as they drift off to sleep. Dd recently learned how to say "mama" (finally ) so now she lies there saying "mama, dada, mama, dada" over and over again getting quieter and quieter. For the past two nights I've been trying to read with a headlamp while they drift off to sleep as they've been taking about 45 minutes to get to sleep so there's been a lot of me giving them "the eye" and telling them to lay down and close their eyes. I get the biggest grins and smirks. Little monkeys .
