As in previous reports from the RISK study, there was a shift in the types of bacteria present in the ileum of children with newly diagnosed Crohn's disease.
AAP Car Seat Safety Guidelines: Rear-Facing Until Age 2. 1  Although the new baseline is now age two, the AAP has advised parents since 2002 to keep kids rear-facing until they reach the height or weight limit of their car seat.
A child can be either too heavy, too tall, or bothâbut all of this depends on the specifcations of the car seat. Each car seat has its own height and weight limits for rear-facing children. Most convertible seats allow children to sit rear-facing up to 35, 40 or 50 pounds. The height limit for most rear-facing car seats is that there must be at least 1 inch of room between the top of the childâs head and the top of the car seat. This inch ensures that as the child slides up the seat in a crash, his head will stay protected.
