It is not a strange situation. My two youngest are 15 months apart. The baby will be 5 in June. I still have the flabby tummy but am thin every place else. I am very athletic and am now enrolled in a boot camp class. As much as I eat healthy and workout, it still seems to be there. The only alternative is to have a tummy tuck to get rid of the extra skin. THAT I am not doing. It will just have to stay for me.
