I got these for my son when he was 4 months old and it was instantly his favorite toy. It was the only toy that his weak and uncoordinated grasp could master and I particularly love the padded links because they were gentler on his gums. At 6 months they still remained a favorite because they were the perfect teething toy. I highly recommend this product. You can get it much cheaper at your local Target or Walmart, though. They're also great for attaching toys to the stroller, car seat, etc. so they can be used on a regular basis even after your child is no longer interested in playing with them.
