Universal-baby-car-seat are designed specifically for newborns and young infants, typically from birth up to about 1 year of age (or until they reach the weight and height limits specified by the manufacturer). They provide a safe and snug environment for infants who cannot sit upright or support their heads on their own.
While infant car seats are suitable for most children within the specified age and weight range, it's essential to keep in mind that every child is different. Factors like weight, height, and individual development may vary, and some children might outgrow an infant car seat sooner than others.
These guidelines will provide information about the seat's maximum weight and height capacity, as well as any age-related recommendations. Once your child reaches the maximum weight or height limit or demonstrates signs of outgrowing the seat (e.g., head reaching the top of the seat or exceeding the weight limit), it's time to transition to a different type of car seat that is appropriate for their size and age.
Convertible car seats, for example, can accommodate both infants and toddlers in a rear-facing mode initially and then be converted to a forward-facing mode as the child grows. This type of car seat provides extended use and may be a suitable option for children who have outgrown their infant car seats.
