I've never been a fan of plastic feeding bottles for my baby. But one made of glass is either limited or expensive (had a hard time looking for one retail in California as well). It was a cause of concern when I noticed that sterilizing of plastic bottles by boiling(!) based it on tradition was commonly used at our household. And sure enough when you forget about it and overboil the bottles, it melts or deforms meaning the plastic composition has been compromised and could leak.
Good thing there are still glass bottles being sold here. The particular one we bought (since it's the only one we found) is the Pigeon brand. But its almost Php 400!
So ok, you don't skimp on your baby's health, the issue is the downside of baby bottles, once baby learns to walk around or feeding outside the crib, bottle slipping occurs and breaks it. Now sure, you can replace it again but with the plastic one going as low as Php 200/3pc pack (Disney pa!), you'll really be tempted to go for that.
Recently, I found at Toytown, Evenflo (made in Mexico) distributes glass bottles as well for less than Php 250. Now I started to replace my baby's plastic bottles one by one every payday and would matter much even if she breaks it. It looks retro too, hexagonal in design and the cap and rim reminds me of the old bottles.The only issue with Evenflo is it seems to have a lower quality plastic rim and cap compared to Pigeon and has a very small hole on the nipple. I'll retrofit a Pigeon nipple on the next grocery round.
I'll keep the remaining plastic bottle when I complete 6 of the glass ones, to use for travel.
