Achieving and maintaining the motivation with young kids?

[MrsFabuloso]

How do you do it?? I am desperate to lose weight. I really don't like myself right now, how I look, how I feel, the role model I am portraying for my kids is terrible (well amybe not terrible, but it's not great!). I know what I need to do....how I should eat and exercise to lose weight. I have been healthy and slim(mer) before. I don't want to be unrealistically thin. But I just can't keep up my mojo. I get it sometimes for a week, sometimes jsut a few days, but when I go back into bad habbits I fall hard and it takes a few weeks to get back out of the hole again. I think I know my triggers. I have some strategies to deal with them. I can do it, have done it before. I have lost 10kg before (before I was so overweight!) so I do have the capacity to lose a fairly substantial amount of weight, but now with kids, it all falls apart so easily. I can't exercise with them in tow. Going for a walk with them is the slowest most painful thing I do in a day! What would be a 5-10min walk for me to the grocery store is a 25 min trip from hell with the 3 of them. DS2 is a cat napper and won't sleep longer than about 30-45mins at a time int he day time. He also likes to be held alot. He also feeds 2-3hrly, for about 20-30mins at a time. When I'm not holding/feeding him, I'm trying to get things cleaned/hung out/cooked and race around like a bat out of hell. If I have the chance I try to spend good quality time alone with my big kids, either at the same time, or one at a time. Or I'm having a shower which is the only peaceful time of the day for me, or I try to spend time with DH, which unfortunately these days is all too little.
So how do you manage to prioritise you? When all of these things need doing. There's so little time in the day! Most of this stuff has to be done. It can't go by the wayside. I have to cook food for everyone. I have to feed the baby. I have to spend time with my kids and hubby. But there has to be a way right?? Lots of people manage to do it somehow. I feel like I really want to lose this weight. I think about it alot....but maybe if I can't od it I don't want it enough...?? HELP!
