Dear L.,
I'm going to go against a lot of what I've read, although I didn't read all the posts. You have a gym membership~use it! You're paying for it, so make it a priority while your son's at school. Let him help you with the house-cleaning, it's a GREAT opportunity to teach him what you do & how you do it, so that as he gets bigger he can help you more. For now, he'll probably have to do little things, but he'll love that you're showing him something new! (My 5 year old thinks it's great when I "let" him help me with dishes or laundry!) Also, take him shopping with you. Bring a book or two along, or maybe a toy, so that he's not bored. Tell him the names of the things you're getting. (ie~these are carrots. They're orange.) This is another great way to integrate teaching into daily life. Kids are like sponges, they soak up everything when they're little, so inform away! Don't skip breakfast, even if it's a mini-bagel with pb. and a small glass of milk. Also, eat less, to eat more, to eat less. Stay with me here ~ eat less when you eat, eat more frequently, eat less overall! There's a lady at my gym who works in the childcare area who is VERY thin! She said that she doesn't do much working out, but she does walk a few miles (3-6) every day. She said that other than walking, she doesn't really do anything special. However, she does eat EVERYTHING in moderation, AND she eats every 2-3 hours. That sounds often, and it is, but if you're eating that frequently, you never get REALLY hungry AND your metabolism doesn't spike & drop the way eating three meals a day does. Also, this means you can eat a piece of fruit here, a handful of light popcorn there, some nuts at another time ~ you can fit all your foods in over the course of the day! Good luck with losing weight. I joined the gym a week and a half ago, and I've already lost 3 pounds, but then I'm going EVERY day during the week (Monday-Friday.) If your gym has free childcare use it on the days your son doesn't go to "school" so that you're doing something EVERY day! If not, take him for a walk, go to a playground, do jumping jacks in the living room with him ~ be active with him, so that he sees your example!
I'll be praying for your weight loss success! :)
