So I am official up 30 lbs since this whole deal started. I know I am have twins so I should put on about 30 to 35 lbs but I still have about 6 weeks to go. Walking is now getting hard and the girls still want up and attention. I swear they dance inside me you can make out little hands and feet as they push for more room. my Question is has any one used a belly belt or sling did it help?
