Night Twelve

So, the good new is that Isabella is starting to realize when it is bedtime.
I have been keeping the same bedtime routine for a week now so she clues in when I go into her room and turn on the sound machine and start our routine.....
Bad new is that she is starting to cry during the routine now, while I'm nursing her, when I put her down and after I leave the room. This is making for alot of crying and not enough sleeping.
It took me an hour to get her to sleep and then she was up at 1am, 4am and 8am.
Not sure what is going on. I think she might be teething again but when I am holding her or when she is playing she is fine so even if she is teething, I think it is more of a separation anxiety than anything else.
Her naps have been off which could have something to do with it as well. Earlier in the week, it was freakin' cold outside (-30/40's) and since I didn't have anywhere to be, we stayed in. This was good as I was able to put her down for 2 solid naps (sometimes 3) a day and I did see an improvement in her night time sleeping. But life goes on and later in the week I had to go out and I found she wasn't napping as well in the car as she did when she was younger. So I'm sure this is contributing to the night time craziness as well but what am I suppose to do? I have things I have to do, I just can't stay home all day everyday so she can nap. I am however going to start scheduling my time better so I only have to go out either in the morning or the afternoon. I'm not going to book both my mornings and afternoon like I have been so we are out twice in a day. She obviously can't handle that and this way she will have at least one good solid nap at home in her bed.
The things we do for our kids!
