I said in the other thread, LO seems to love the Day-Night Owl toy by Skip-hop.

He also likes his floor activity gym, he likes the toys and the mirror especially and my nephew loves it too - he's old enough to play with the music portion of it. http://www.amazon.com/Tiny-Love-Deluxe-Lights-Activity/dp/B000067K0L

One of MY favorite toys of LOs that i hope he really likes when he's older is his knit elephant - so cute!
