Getting fit and motivate, how do you?

So with this new year coming. I went back and organized all videos and photos of 2013. I was really working hard on taking out bad foods and drinks from my diet and slowly getting myself to lose weight. Well come July I was getting frustrated that all my new clothes were getting to tight, didn't make sense to me. Then I found out late August we were pregnant. So my whole workout plan was thrown away. I looked into aqua fit and other light things, but nothing worked with our schedules.
While being pregnant I actually haven't gained any weight since 3 months. Mind you I have been sick and not eating a lot if anything, which is incredibly bad I know. But when I eat I try to avoid fatty foods and stick with water or milk for drinks. This also being anything else makes me sick. I hope to do some light work outs each week and when the baby comes get back into getting fit and healthy. This is a BIG challenge for me as I love certain foods and drinks. I think this is a challenge for all though.
What do you do to stay healthy and get fit? I don't want to go on a strict diet or do anything to dramatically because lets face it, 4 kids and one being a baby I won't have the time to prepare those healthy meals and honestly will just forget to eat like I do now as I am so busy getting the kids food ready.
For the holidays I got what I wanted, a slow cooker. I hope to use this quite often as my cooking abilities are not as great as their dads. I am the baker of the house, I love to bake, but never eat the sweets, weird eh! Do you have any good cook book recipes for slow cookers? I got one for the holidays and it looks confusing but is still pretty awesome as it is very details and descriptive.

To motivate myself getting fit and healthy I made a video/slideshow of myself over 2013, I compared it to 2012 and wow did I gain a lot it feels like in 1 year. I look at this video and it so far has motivated me and hope it will motivate me more. Not only in weight and health but it beauty and joy as well. I mean some days I just don't feel like getting my hair done and make up, but I look at those photos and remember how great those days were and want more like that.
