We've always used the same Fisher-Price booster seat since my DD was 5 months old. She still will sit there for meals and some snacks but she also likes to climb up onto the regular chairs and at 21 months can basically do a lot of eating at our table in the kitchen. She probably couldn't reach at our real dining room table but we hardly ever sit there unless guests are over. Though, now that I think about it we will need to sit there in a year when the new baby is old enough because the kitchen table only fits 3.
So, if you've only had a booster, did you ever get a stokke or other more comfortable chair for a toddler? Am I going to reach a practical shelf life for the booster or did you keep using through the late toddler stage? Is it worth it to get a higher end stokke at this point?
