AAGGHH!!!

Seriously?? What a day! This morning, I take the girls to the store and Natalie has a complete meltdown over nothing. She is crying and screaming in the store so I take her out of the cart and give her a hug. We have a little talk...she's all good,I'm worn out. I run around the store, get everything done and head home. Then, I'm making dinner in the crockpot and the ground beef that I JUST bought at the store is ROTTEN. Ok...really? I don't have time to go back to the store before the kids go down. So I throw the rest of the food in the crock pot and put the rotten meat in a bag to take back later when Shane is home. Hopefully I'll have time to take back the bad meat and get some new meat and then add it to the soup and still have it taste good. So then after lunch I put the girls down for a nap and eat some lunch. Natalie wasn't sleeping at all so I went up stairs to help her fall asleep. Usually I'll put her back in bed and sing to her and she'll go right to sleep. Today she did not want to sleep! It's so frusterating! It took me an HOUR today to get her to fall asleep. I just don't know what to do. How do you get an almost 3 year old to sleep during her nap? She is such a good sleeper, once she actually falls asleep. At night she is perfect. It's just the middle of the day...I can't get her to sleep by herself. If I just leave her and let her play in her room by herself she is super cranky for the rest of the afternoon. Anyone have any suggestions??? The day is only half over and I am completely worn out!!
