Anyone can recommend a good teether for my 5 mths old baby?

Some parents have cut open their kid's giraffes and found mould inside, so I'd actually recommend the standard gel teethers. These can be frozen or chilled in the fridge to provide relief for baby's swollen gums. Pigeon is a trusted brand, and I'll be getting these gel teethers for my baby. http://www.whattoexpect.com/forums/april-2015-babies/topic/beware-sophie-the-giraffe.html
