Busy!

I am too busy living and surviving life to blog about it. But....can someone (anyone?) reassure me that almost 15 month olds acting like crazed psychos with their four canine teeth coming in and no other symptoms WILL get better and stop fussing all the time and stop, at least when they are 5, jumping on tables and stop destroying stuff and stop taking a small nap early in the day and then refusing to nap later and other such things? Thank you because I have lost all perspective.
