Gro Company founders Rob and Ouvrielle Holmes invented the Grobag baby sleeping bag after trying to get their newborn son Sam to sleep. Around the time their second child was born, the UK-based couple decided to produce Grobags for other new parents who might be searching for an alternative to fussy baby blankets and sheets. Launched in September 2000, Gro instantly made an impact: today, more than 95 percent of British parents use baby sleeping bags. With a line of products that includes newborn swaddles, color-changing Gro-egg thermometers, clocks, and nightlights in addition to its signature sleep sacks (available in sizes 0-6 months, 6-18 months and 18-36 months), the Gro Company has demonstrated an unflagging commitment to making sure that little ones everywhere sleep soundly and safely.
