Wasn't too expensive about $50 when we got it right now it's $60. We got it for Christmas for Peyton when he was 5ish months old. He loved it used until a few months ago when he learned how to climb out of everything. Wouldn't suggest a walker really, Peyton didn't use his too much. A swing! Peyton loved his swing. And as far as toys, he liked things that made noise/lit up and that he could easily fit in his mouth.
One of those, when Peyton really couldn't crawl or anything he loved laying in this thing to play.
And Peyton had one of these balls, it was great:http://www.walmart.com/ip/VTech-Move-Crawl-Ball-Pink/14321369
