Head and Backaches

I think I'm 15 weeks now. I haven't kept up with it like I did with AnnElise. This pregnancy is so much the same, but also so different than with AnnElise. I keep getting random headaches and my back has hurt almost constantly. My back may be due to being pregnant and picking up a 23 lb toddler all of the time. With AnnElise, I had absolutely no nausea, no backache, no headaches, and didn't feel pregnant at all. I don't really feel pregnant now. I'm kinda used to having headaches and backaches on a regular basis, but now I'm very limited in what I can take for relief. Its frustrating. I am getting my energy back which is really good. It was hard taking care of AE by myself with no energy. Today, I'm very thankful that I have my energy back. AnnElise has been into everything and making a huge mess. Just today and all before her first nap, she had put her shoe in the toilet, thrown away her sippy cup, found a cup on my night stand full of water and spilt every drop of it on our kitchen floor ( she managed to carry it all of the way up the steps without spilling a drop of it), threw a bowl of veggies on the floor, stood up on top of her musical table then hit her head pretty hard when she fell, took mounds of dirt from a potted plant to decorate the couch with, took off a dirty diaper and sat her nasty butt down on the steps (this was a first), and then finally slept for about 3-4 hours. She also learned to walk backwards and was pretty proud of herself. During every incident, she never threw a fit, just wanted to make a mess of everything. She did it with a smile on her face the whole time until she got popped for throwing dirt on the couch. I did put her to bed an hour earlier since she took a long morning nap and missed the afternoon one. I love my little girl so much. She is very easily entertained. Today was extremely out of the ordinary, and hopefully not to be duplicated ever again. Its hard to be mad at her when she just laughs at everything. So now my migraine is making me nauseous (its making me gag) but pregnancy is making me hungry.
