$2.99
rattle/teether from Babies R' Us
$.99 + s/h
musical giraffe off ebay
$3.99
Gymboree winter hat off eBay (bought this back in 2002 for Ryan)
$.99
Little Tikes hammer (I bought it at Toys R' Us, but it's the one on the right); Nate loves to bang it and chew on it...although sometimes he hammers himself instead.
$5.99 stacking cups & penguin from the supermarket in 2002 that we use in the bath (don't have time to dig up a photo right now).
I think our First Years booster seat for the dining room was $19.99.
Honestly there are very very few items for all 3 boys that cost MORE than $20. The crib/mattress, crib sheets, Bjorn, Kelty backpack, playyard/gates & lots of clothes & toys were all hand-me-downs from nannying. Only as they've gotten above size 4 for clothes (especially pants & sneakers) and needed beds have we had to spend anything significant.
I think carseats are the big ticket items.
