So, I was on Craigslist and I found this swing. Which got me thinking, why don't they seem to make baby swings like this anymore? (With them sitting more upright) Can babies use this type of swing past 6 months old? Aribella loved her baby swing but I think I read they shouldn't use them past 6 months old and either way I think she's outgrowing it.
