we used to go fo a walk everyday with Ryan at nap time as this was the only way to get him to sleep longer than 30 mins. i wasn't a bw member then and didn't know how to get around the short naps. i would go wind , rain or sun .after a few weeks i noticed a pattern that he would fall asleep at the same spot on our walk , so after a week more of this , i tried putting him in his cot at this time, and he napped in his cot from then on , and took long naps. this was probably coincidence but the walking to nap worked a treat for us , just to figure out a correct nap time. we chose a route with a bumpy road , guaranteed to fall asleep. also though Ryan refluxed bad at this age and as his pram was elevated this helped with the longer naps , he hated his cot elevated and i think he was finding it hard to stay asleep. sleeping in the pram with motion never came a bad habit for us.
