slowly i was able to start putting him right next to me in bed without holding him in my arms and he'd stay asleep a bit longer. to be safe matt would sleep on the floor or in the library and i'd have grant in his place in bed. but still, naps during the day had to be in someones arms.
then i started the "training" thing. in one day he was able to sleep in his own bed, right by us in the bedroom. and he's been just perfect at night, slowly making his way to sleeping 6+ hours. but naps wouldn't last long if i put him down on his own. for just a little bit training helped there, but i think it just took time for him to realize "oh my mom will come and get me when i wake up."
i love this stage, he is playing and then silently he starts telling me he's tired, adding little noises here and there. just the sweetest little faces. so i pick him up to cuddle and he's out. and now he knows i'll be back when he wakes up and it's alright if i put him down.
