My new sleeper for 18 month olds

I have almost outgrown all my other sleepers (my toes are right at the end), so my Dad got me a new sleeper for 18 month olds. Their sizing chart is as follows for 18months: 20-24lbs or 71-79cm long. It's made by St. Lawrence Textiles who make the BabysOwn Brand. I like it a lot. It's a little big for me in the legs still, but I'll grow into it.
