1st let me welcome you to Spark People! I have found alot of support here when I have needed it and hope you find the same! Give yourself credit for being a mom of two little ones, that takes alot of energy in itself
I only had one child who is now grown and so I applaud anyone who has more than one child. I can picture you running around the house after your 3 yr old while strattling your little one to your side and trying to find time to "RUN" LOL
Here there are exercises to help you and even you will find your 3 yr old trying to copy your moves will encourage and make you smile!
