Love all Emerson and Friends pajamas! These fit 3-4x longer than any other brand. My baby is a big boy, and wearing 12months (in other brands) at 4 months old. He has been able to wear his 0-3 in his Emerson pajamas until now- now the 3-6 and 6-12 fit better. They are 3x more expensive but they fit 3x longer and are so much softer than other brands. These are very comparable to Little Sleepies, although Emerson seem to be a little thicker so I like these better!
