I feel like I've not seen DS2 today! He'll happily nap on me for up to 3 hours, and be ready for another after 90 minutes of awake time (irrespective of how long his nap is). He'll only contact nap, and if I put him down he'll inevitably be awake in ten minutes. His night time sleep is appalling at the moment as he's congested and waking because of that, so I've not interfered with his desire to sleep at the moment, but this is what he's like without illness... I've no memory of DS1 at this age, but should I be waking him at some point? I do quite like his eyes!
