But, back to your question about sores in the mouth during oral sex: If the person performing oral sex has a canker sore in her/his mouth, and s/he comes into direct contact with her/his partner's semen, vaginal fluids, or blood, s/he may well be increasing her/his risks of contracting HIV from her/his partner if s/he is infected.
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.
1 If a baby under one year of age grows too tall or too heavy for an infant-only seat, a convertible seat with a higher rear-facing weight limit (over 22 pounds) is recommended. 2  Convertible child safety seats may be turned around to face the front when baby is over one year of age AND at least 20 pounds. If the child safety seat is too upright for the baby, and the base is not adjustable, place a tightly rolled bath towel, or part of a foam pool noodle, under the front edge of the child safety seat to tilt it back a little. 2  Do not recline the rear-facing child safety seat too far back or the child could be ejected.
