Tummy Tuck before having kids is safe and will not affect future pregnancies, however I recommend the majority of my patients to wait until after they are done having children as pregnancies will stretch out your abdominal muscles and skin, changing your results. I would recommend consulting in person with a Plastic Surgeon to further discuss the procedures and your goals. Good luck!
A tummy tuck that includes tightening of the abdominal muscle wall should not be done until the patient has finished having children. However, it is safe to have a tummy tuck that is to remove excess skin such as after losing a lot of weight.
