We are needing to move our 2.5 year old out of her
Marathon because the 8 month old now needs it since she is almost over 20 lbs already. The 2.5 year old is 41 lbs and 40" tall. She's a big girl but needs to remain harnessed until she is more mature! I've read some great reviews on
Graco's new
Nautilus, would this be a good choice for our big girl or does anyone have other suggestions?
