thats my concern too, worried cant sleep without sarong. but still finally gave in to my mum coz we want our boy to sleep/ nap longer. my elder girl last time only naps for 30mins, really cant do much housework, the most just finish washing the nappies & she's awake liao.
my boy now also cant sleep long when we are outside, only 30mins of cat nap. i hv already remove the sarong but still hv to put him in the rocker to sleep. hv tried moving him to the bumper mat after he's asleep but my attempt yesterday failed! think hv to let him fall into deeper sleep then can move him. at night is so much easier as he falls asleep on his own after his last feed, wish nap time is this easy.
