Anyone found a tough dummy that a 2yr old can't chew a hole in? DS is costing me a fortune. Gave him a brand new silicone one tonight and it had a hole in it in 1/2 an hour. Have tried latex and they have lasted a bit longer but have still gone in the bin. He has always had NUK brand. Need something tougher. And before everyone says get rid of them, yes I am going to get rid of them completely but still need them for sleeping at the moment while the 2 yr old molars are giving him trouble.
