Ds and I are battling over day time naps. He used to have a 45/1hr sleep in the morning and one in the afternoon. Now he just stands up the minute I leave the room and kicks off until I give up and rock him. He's been up there 30 mins as I type and is still yelling (have popped up twice to check he's not stuck or anything but haven't gone in). Do you think at 9 months he might only need one big sleep and maybe I should put up with him being grumpy and stretch it out til lunch to put him down?
