Hello. I have reviewed your query and here is my advice. No one wants to scare a new parent, but you also don’t want to overlook any possible problems. Keep in mind that a cute little rounded belly is absolutely normal for a toddler, and your child more than likely fits into this average shape. On the other hand, if you begin to notice that your toddler’s stomach seems more rounded than it usually does, keep an eye on the situation. It is quite possible that they are heading into another growth spurt. In this case the excessive protrusion will appear flatter within a couple of weeks. They could also be experiencing a bloating problem. Watch for any discomfort that coincides with the exaggerated belly. This could be the result of constipation or some type of food intolerance. Children who are lactose intolerant will experience diarrhea and cramps in addition to the bloating. Your doctor knows better and please watch and work with your doctor. Hope I have answered your query. You can contact me for treatment options. Let me know if I can assist you further. Regards, Dr. K. V. Anand
