Any recommendation for teething toys for a 4mo baby?TIA!

Got this as a gift for a friend. Her baby took well to it. But every baby is different. Just sharing for your consideration. :) MAM - Bite & Brush Teether http://www.dearbaby.com.sg/shop/256-shop/276-feeding/329-teetherssoothers/2969-mam-bite-a-brush-teether.html Another popular one is Sophie the Giraffe. http://www.sophie.sg/sophie-la-girafe/sophie-the-giraffe-in-gift-box-1.html
