help my lo used to go to sleep 7 or 8 at latest and now thinks this is just a nother cat nap he wakes after about 45 Min's and is up i tried to stay outside room listen and go in soon as he stirs to catch him right away but hes up he only stays up for an hr and is no prob to put back to sleep he gives me the sleepy signs and is happy to go to bed but what the world is going on how do i fix this one or will it just go back to normal. it started when dad had to work late couple of nites so never saw lo and when lo heard dad home would wake and see him then go back to bed. im ok with it and lo is not any worse at nite or day but should i fix it before it becomes a prob.
