I want to buy DS (4.5 months) either a Winkel teething rattle, or a Skwish toy. He had great fun with both at a friend's house, as he was able to immediately pick them up and chew them, which he can't do with other things yet.
Which should I buy? I'm only going to get one or the other. I'd probably be inclined to get whichever is going to last him the longest.
Any recommendations welcome.
