One of my 1 yr olds is 15kg in weight and I'm wondering about car seat safety before she reaches 4. She's nearly 2 and is currently in a stage 2 MaxiCosi car seat but these are recommended up to 18kg. Usually they go into booster seats from around age 4 but she's clearly going to be over 18kg a long time before reaching that age. Do you know if they are supposed to move seats or if the stage 2 is fine to continue with?
Also, she's heavier than I'm supposed to allow in my travel cot but she's ok for now. She IS getting a bit long for it and her mum mentioned getting a bed for her at home but WWYD in this situation for nap times?
Any advice would be great, thanks
