Average times between heat periods is seven months but some dogs  can cycle as early as every 4 months, some once a year.   Lengths of heat cycles and intervals between cycles are different  for each dog but most dogs hit somewhere close to the averages.

Carseats and boosters should NEVER be installed in side-facing jump seats. Unfortunately, that means that children under 8 years old (about 80 pounds) should not ride in these types of seats. Children should never ride in the cargo area of a pickup. Rear-facing seats in wagons vary.
However, there are some car seats that are generally made for children up to 40 pounds and, at that point, they will usually go into a booster seat in the car. Most booster seats are made for children to start using at 40 pounds.
