How lucky you are....
.....that you have these forums to turn to! Back in the Stone Age when I had my kids (they're 28 & 27), I had NO ONE to help me!!!!!
That's why I had to jump on your question.
Start with baby steps.....maybe just start walking! Get out your stoller, put the little nipper in it, go to the mall, and walk and window shop. Or walk outside. Get into a habit of doing something, and make yourself a schedule to follow. In other words, make appointments for your workouts, and TREAT THEM SERIOUSLY!!!!!!!! Then you can work in your tapes gradually.
You have to start small, and then you won't be quite as overwhelmed. Also, break your weight loss goals into smaller bites....start with five pounds. Then another five. And don't try to hurry it.
And don't forget, we are here to cheer you on!!!!
Been there, done that!!!!!!!
Good luck
You CAN do it!!!
