ds was a HUGE spitter upper- spit up constatnly until aobut 9 months. then it really tapered down. lately, he's been spitting up milk- he's on whole milk for a few weeks already. spits up maybe once every 2-3 days? is this still normal? forgot to aks at 12 mo visit, and hopefully won't be bakc at ped unti l15 month visit.
