First of all, that’s the idea – you are now reminded to be careful to light. BTW, that seems to be the source for adding a light for each child – since the kimpiturin was not supposed to get out of bed, she couldn’t light…
secondly, on yom tov you can light anytime through the evening. Our minhag, in fact, is to light right before kiddush so that the shehecheyanu applies to the lecht as well and the wife can answer amen to it without it being a hefesek for her for kiddush.
bottom line – ASK A SHAILA, NOT YW COFFEEROOM!
