Do the Gerber Size 2 (Large) Latex Exist Anymore?

I have searched everywhere for these! We originally got them as part of a Gerber bottle set at our local grocery store. They seem to no longer exist. Gerber online and drug stores have the Size 1 (small) latex or the Nuk orthodontic kinds but my baby will only take the large straight latex ones. I spoke to a supposed specialist at Gerber yesterday and the person was clueless. If you know anything about how I can get a large rubber nipple with a standard shape (even other brands are fine), please let me know. Thanks!
