Being a busy mom myself, I would suggest that you take 9 months to settle into a routine prior to having any surgical procedure.
When the time is right, consult with a board certified plastic surgeon. (Christine Sullivan, MD, Columbus Plastic Surgeon)
A short scar tummy tuck with muscle repair and liposuction of the sides will produce a very nice result. Based on your photos, you would be a good candidate for a tummy tuck and liposuction on the sides to improve your trunk area.
Pregnancies can cause skin redundancy and abdominal muscle separation which will not improve with diet and exercise. I would wait ~6 months before any type of procedure to allow your body to recover from pregnancy. (Eugene Kim, MD, Beverly Hills Plastic Surgeon)
First of all, I’m amazed at your progress only 7 weeks after your last child. While it is great that you are already back to your normal weight, the process that your body goes through in getting back to normal physical and physiological shape takes quite some time.
I recommend that you wait at least 6 if not 9 months after your baby is born before you go and get an evaluation by a board certified plastic surgeon to assess the best way to get your desired outcome.
You might benefit from an abdominoplasty, or liposuction, or even possibly a non-invasive CoolSculpting procedure. (Adam David Lowenstein, MD, FACS, Santa Barbara Plastic Surgeon)
Excellent candidate for an abdominoplasty.
From the photograph it looks as though you would be an excellent candidate for an abdominoplasty. I don’t see a lot of fat that needs to be liposuction but that would require a personal visit. (Vincent N. Zubowicz, MD, Atlanta Plastic Surgeon)
