I have a good group of kids, but when they are hungry or tired all hell breaks lose! Im finding it really difficult to prepare lunch and then after lunch get everyone down for a nap calmly. They all are under foot screaming for lunch and then start screaming for nap time. I have 4/5 still in diapers so it is a process to feed, change and get them all ready. Any tips? I am just so flustered after they go down it makes it difficult for me to unwind and get things accomplished during nap time.
