Welcome!
I'm Aphil, and I had my third child in August. He just turned 6 months old.
Basically-I got huge with #1, lost the weight through diet and exercise...got huge again with #2...lost the weight...now I am working to lose the weight for the final time, after baby #3. (THE LAST!!)
It is a struggle...and there are definitely difficulties that mothers with babies and young children face that those with older children/no children don't-nursing, lack of sleep, etc. and it is great to find support here.
