54% off RRP (and much cheaper than CW) these are the medical grade PPSU bottles (BPA & BPS free), really robust I've found, with multiple boilings & use daily by the little vomit comet.
Definitely for 3M+ as we bought our first pair by accident when the baby was 6 weeks old & she almost drowned!
Pasta'd details from Amazon:
