These buckets are fantastic for children who are stable on their feet - I would not give these to babies not able to walk and stand comfortably or just learning to walk/cruise, because they can fall on them and though won't get seriously injured most likely, it would hurt (and might crack the plastic).  They are rated for 18 months+ for this reason no doubt.  Excellent toy, my older (4 yo) daughter also likes to use the buckets individually for carrying/organizing things as if she's shopping, etc.
