This bundle pairs Boon's innovative Nursh silicone baby bottles with conversion straw sippy cup lids to take your little one from bottle feeding to big kid sipping. The Nursh bottles feature a 100% silicone collapsible pouch design that squeezes out air as baby drinks to reduce gas, colic, and burping.

Both the silicone pouches and conversion lids are top-rack dishwasher safe for easy cleaning.
