A member asked:

How many times per day should my baby eat, and how should I deal with any feeding problems?

Dr. Laura Webb
Pediatrics 13 years experience
When they are hungry: As infants you should feed your baby whenever they are hungry. Generally this is every 2-3 hours. As they get bigger they will eat more with each feeding and the time between will lengthen. But even 3 and 4 mo babies will eat every 3 hours or so during the day. Count number of wet diapers if there are not 6-8 daily see your dr. If you are concerned about any feeding problems see your dr.

Depends....: There are many types of back surgery for many different back conditions so answering specifically will be difficult; however, generally you can expect to be up and walking within 1-2 days after surgery. You'll also likely be limited in the amount of bending/twisting you are allowed to do, maybe even in a back brace. Pain/discomfort should be expected but diminishing. You may also have a catheter.

Not usual for disk: With the muscular atrophy and neuritis, it might be best to undergo further testing. There are many possible causes, including diabetes, autoimmune, endocrine, to mention a few. At your age, a complete workup is indicated.
