ds2 (3 1/4) has had quite a few nights recently of going to sleep without nursing, due to circumstances of being out and about when he fell asleep.
we were recently on vacation for 2 weeks, and he did more night nursing during that time. i just figured it was due to being displaced from our norm.
he doesn't night nurse much these days. the four of us switch positions in our king-size bed during the night, and sometimes ds2 will awaken on the other side of dh from me and clamber over dh to reach me. sometimes he murmurs "i want to neenoo" but then falls back asleep snuggled up to me before he can accomplish that goal
... i love how it feels when he snuggles up!
