Is a Mommy Makeover what I need? Or am I being selfish and lazy?

I'm 33 and after having my two babies 16 months apart I have noticed my breast are not as full, I have a huge classic cesarean scar and just all around and old looking belly.  I have mentioned tomy spouse that I would like to do a mommy makeover Bbut he thinks that i need to workout more, eat better and I will feel better about my body.  I am 5'4 156 lbs and fairly active.  I know  I can drop more weight but I don't think that will remove the fact that I feel like my breast and tummy are not sexy anymore.   I am living in Nolanville, Tx and work full time..if I did the surgery how much time off would I need? Will I be able to pickup my babies and take care of my family?   Thank you, Undecided in Tx
