Lately getting a good night sleep has been hard.
Really it's mainly for 2 reasons:
#1. 
#2.
Yes these two particular kids are the problem. Up many times a night. Once I get one down the other one wakes up. Griffin has night terrors and Savannah just seems to like to get up several times a night crying for the fun of it. I can't blame them entirely for being tired, but they sure don't help anything. This too shall pass.
