I cant really explain it, but I'm living it. Most weeks I only lose 2 lbs but lose about 5-6 inches over my total body. One week I didnt lose any pounds but lost 6.5 inches. Weight can change so easily due to water weight gain, or bloating due to your cycle each month.
I weigh myself and measure every Monday and keep track. Seeing that weekly change is really motivating!!
I also have 2 small kids at home, two girls ages 3yrs and 7 mos. So I know how tough it is to get out and exercise, but you have to find the time. I do the bodyflex video and the Walk away the pounds by Leslie Sansone. (?)
They are both about 20 minutes long (1 mile tape, the 2-3 mile is longer) and my 3 yr old loves to do them with mommy. lol Shes lucky though, she drops out and picks back up whenever she pleases.
Dumbbells are also easy to do with small kids around, just a few reps in between story time and fixing meals makes a BIG difference.
Good luck
