WIY – I want to say that in principle I agree with you about taking each chodesh and YT in its time, but Pesach is a holiday that has aspects to it that do require planning and preparation beforehand to avoid making bedikas chometz and changing over at 3:00 in the morning the night before Seder.
Some families can start on R”Ch Nissan the cleaning process but most need time to do the easier (and less difficult to get to) places in the house before approaching the living areas such as the dining room and kitchen, where the majority of the chometz is found. Children have to be educated from the beginning not to bring chometz out of these areas. This is something that makes Pesach cleaning much easier, although exceptions are known to happen, so vigilance is a must.
When my children were smaller, we used to begin cleaning the sefarim already from Teves – on motzai Shabbos when they did not have to go bed early – a few shelves at a time. This way by the time we go to Purim, we were basically done except for the shelves that had siddurim and chumashim on them, since they were used and could have been around chometz. My husband is makpid not to bring sefarim around chometz year-round, so it does make things easier, but the dust does accumulate and it is good for the shelves to be turned over to prevent a permanent roundness in one direction.
I also like to clean the top shelves in my closets (here in EY they are not built-in or a small separate room like in America), but the idea still applies – clean up the things that I am not going to use so close to Pesach. I recently had a few days off from work and organized clothes that my younger kids will get as hand-me-downs from my older kids. Now those clothes are all organized and I can actually see what I have that is useful for YT in advance. Makes shopping much easier in those last days as well.
Yes, ladies (and men who are able to help for this) Pesach is almost here. Happy cleaning and organizing, and remember DUST IS NOT CHOMETZ!!! Don’t make yourselves crazy!!!
