My surgeon says a mommy makeover will take 8 hours. Is this safe?

Mommy makeovers combine several procedures in a single setting so they are longer cases. Board certified plastic surgeons routinely perform these procedures safely either in accredited surgical centers or hospitals with the appropriate team members (anesthesiologists/nurses/assistants, etc.) and appropriate postop/overnight monitoring. 

A Mommy Makeover typically combines procedures addressing the abdomen and breasts but can include other areas as well. The surgical time will depend on the number of procedures done and the areas addressed. For example if there is liposuction performed on the back as well as procedures on the front, the patient will need to be turned. This takes more time than some would think since the patient is under anesthesia. In all a Mommy Makeover could take 8 hours in some cases. A careful review of your health history and candidacy for the procedures is considered to determine risk. This is one of the many reasons why an experienced board certified plastic surgeon is so important.

It's hard to say without knowing a little more about your situation.  How many procedures are part of the mommy makeover?  If we use the standard pairing, a breast procedure and tummy tuck, that could take as little as 2-3 hours or up to 4-5 hours depending on the extent of each part of the surgery.  I scratch my head as to how one could get to 8 hours unless we are talking about additional procedures such as face/arms/thighs.  In that case, the extent of surgery presents a bit of concern and can lead to a higher chance of postoperative difficulties.  I favor limiting surgery to 6 hrs (FL rules allow up to 8) if possible.  That allows for some extra time if needed and limits the difficulty of recovery.  I have found that nearly 100% of patients can be safely discharged to home with a very low chance of issues when following these and other principles.
