Not expecting any solutions really but this is this weeks pet peeve. Have a 6 month old who I trying to get to have more sleep, just managing to sort bedtime routine out, now concentrating on a good solid nap during the day. But just as she is dropping off my 22 month old will shout something and we are back to square one. If I mamaged to get them to nap at the same time, the youngest one can wake after 20 mins and wake her big sister up.
