First post here, the moral of this post is that I think little sleepies purposely makes their clothes too big to cater to the “omg my 4 year old still fits in his 12month romper!!” scene. My son is and always has been at the 50th percentile for both height and weight, for most brands he switches a size up right around the time he hits the age range (switched to 12-18 around his first birthday, etc.) I’ve NEVER had as many problems with a brands sizing than with little sleepies. I bought one romper from them when my son was younger in 3-6 I think and it wasnt bad but I preferred other bamboo. But i’ve always seen the posts of people being obsessed with this brand and so I caved and I splurged on their black friday sale getting convertible rompers mostly in the 12-18 size & 2T. My son just now turned 18 months and is growing out of the 12-18 size in almost all of his bamboo pjs (they’re not super small just the neckline is stretched down a little bit so I know it’s time to size up soon) and i’m slowly switching his wardrobe to 18-24 month. And he STILL doesn’t fit in his little sleepies 12-18 month size. The cuffs on the arms and legs are so insanely scrunched up there’s just way too much unnecessary fabric there. Like they’re fine to wear I just feel like they don’t fit right. They advertise that these are meant to “grow with your child” & “last so long” but I just feel like in reality all their sizing if just off. Like if all your 6-9 pajamas fit 18 month old toddlers but not 6 month old babies doesn’t that just mean your sizing is off? In all reality I don’t get the hype at all, the material is ok but their prints are not anything special and I don’t understand why people worship this brand.
