Yep...I know exactly what you mean! For me those days usually happen when I haven't had enough sleep or I'm feeling under the weather. I know that the kids feed off of my irritability and it spirals downward from there and I do my best ot stay calm and patient...but we are human! I definitely know that when I am energetic and feeling good, the kids behave much better and we all have great days. My only advice is to try to get some rest and a good night's sleep and it will seem much better. Hang in there!
