Runs very small. My grandson is 3 months old, but I purchased a 6 month & way too small. I would have returned them, but had to squeeze him them once as I didn't have any other pjs.

I have purchased a few sets in each size since my baby was a newborn. Now he is in 6m and I will continue to buy them. Great material that doesn't shrink nor fade. FYI: This is with using the hand wash setting on our washer so, results may vary.

The sleeves and arms run way small. Baby is 5 months old and had to size up to 18 month old and still the arms are SMALL. Guess we will cut the sleeves off and make a sleeveless sleeper lol. We needed something for him to get grip support with his feet while in his activity center and thought this would be perfect. Wish I would have saved the tag to return

Great sleepers at a great price.

True to size fit and washes well.

Oh these sleepers are so cute! Super comfy and in between lightweight and heavy. They wash really well too. This is good during the transitions in between seasons when it’s cooler at night. I say these are true to size.

Love the quality of these, soft & comfy. However the pack I just bought, the neckline seems very tight which I did not notice with the smaller size? So unfortunately, I am going to return them.

Excited to try these because they're so cute and a great price. Unfortunately the bottom of the zipper falls directly on my baby's kneecap, so it hurts when he crawls. The fit was otherwise good, but this a problematic design flaw. Returned.

These pajamas are so soft and stay soft with each wash. The do run small though! My baby wears 3mo clothes and the 6 month ones fit him perfectly. Definitely a narrow cut but works perfect for us.

I have no idea if my batch was mislabeled at manufacturing but the 18m would fit my older child that wears 5T so the 18M size is as large as a 5T!!! Very hard to believe that the sizing is this off. I'm really bummed.
