infant-child sizing guide

Sizing guide for baby hats is as follows from Sunday Afternoons web site: Infant 18-19.5", Baby 19.5-21.5", Child 20-22", Youth 21-23" To measure your head, circle the crown of your head with a string or dental floss (above eyebrows and ears). Use a ruler to measure the string and compare to the above chart. I bought the purple, child size one for my 2 year old. She's 5 and a half now and still wearing it! It looks as good as the day we bought it. We love these hats so much all 5 of us in the family have them now- adults, kids and new baby boy! They are light weight, cute, hold up great for use in the pool/ocean (they float!) or playing outside and pack into school bags well for recess on the playground. Love, Love LOVE these hats!

Perfect for a child under 30 pounds. My toddler is 23 months and 24 pounds and it fits great.

Bought a size 0-3 month's for my sons baptism and he couldn't wear it as it was too big. It's even too big for my niece and she's 2 years old. The quality of the outfit however is commendable.

One problem buying on Amazon is the lack of accurate size guide. I based my purchase on reviews, brand size guide (if available by googling) and guessing (not ideal). Exchange is quite impossible (as I stay outside US). So I really wish Amazon can improve on provide a more accurate/detailed size guide. Anyway I took a bet and got size M for my 8 year old son (4 feet tall and 68 pounds)...fits a little loose and long but it's okay as he can grown into it. Otherwise, good material and nice red color. I got a good discount for it so am pleased.

I like the product, but the sizing was way off.  I bought the set for my niece, who is six months old.  I bought "infant" and what arrived was labeled 18-24 months.  So although the quality is nice, it won't fit her until next winter.

I ordered 6-12 months-size for baby who will be exactly 1 year within two weeks of arrival of this item. But then again, the 12-18 months would've been too large. The 6-12 months was bit too tight for the baby.

The costume looks great especially the head-gear.

These swim trunks are great, but make sure you look at the size chart. It gives a breakdown by weight. My little guy is just over 1 and weighs just over 21 lbs. I ordered him an XL, or 24 months and they fit him great with some room for growth. In regular clothes, he only wears 12-18 month sizes.
Below is the i play size chart:

i play Swimwear Size  US Clothing Size  Weight
(in lbs)
Preemie  Birth  4-6 lbs
Newborn  3 Months  6-10 lbs
Small  6 Months  10-18 lbs
Medium  12 Months  18-22 lbs
Large  18 Months  22-25 lbs
X-Large  24 Months  25-30 lbs
3T  3 Years  30-37 lbs
4T  4 Years  38-46 lbs

First of all I have to state that I bought this outfit as a gift, so it has not yet been tried on the infant it is intended for (who is due in 3 weeks).  However, when I chose the size I am glad that I did not pick the Newborn size.  The sizing for 0-3 months did not indicate what weight/length infant the outfit would fit, and when it arrived it states 8-12 pounds, which is on the small size for 0-3 months.  By looking at the outfit I can tell that the onesie portion is on the small side, and the pants are rather large in length/the waist in comparison.  The outfit has a really cute design, and the weight of the material will be perfect for early spring weather.  The material is a t-shirt weight material that would be perfect for spring or fall.  I received this outfit at a discounted price in exchange for writing a review.

I got the item delivered in time for my 11 month old daughter.  I chose size 12/18, and it fits my baby.

We both love the item.

I had trouble figuring out what size to order because it was only by small, medium, large, etc....the size chart only went by age and didn't say what age coorelated to what size. I read the reviews and guessed since someone mentioned the medium was good for their 11 month old. The small was too big for my 6 month old. After washing them they fit a little better and it really wasn't a big deal since they were mostly covered by her dress.

I used the 3 month size as an undergarment for my infant daughter when she was Christened.  At the time, she was around 9lbs and it fit her snuggly, but worked for what I needed it to.  We used the 6 month size for her twin brother.  It fit him snuggly and was slightly short (he was 12lbs and a little shy of 2 feet long).  But, again, it worked for our purposes. Very soft and brilliant white.

After reading the reviews I was worried about sizing my 2 & 1/2 year old daughter who is 24lbs. She's tiny for her age. I ordered the X-Large (18-24M) for weight range 25-30 lbs. Even though she's not in that age OR weight range, the one I chose FIT PERFECTLY! No squeezing too tight, no loose parts, no redness. It was a long road of extensive research & reading reviews. The sizing chart on Amazon is wack. I used the iPlay website's size chart and went up one size from her weight because the reviews said elastics are tight. Super cute pattern/design! Great Prices!

My son has worn this hat from 6 months and he is now 12 months. The infant size fit him perfectly.

I made the mistake of not looking at this company's sizing chart. My baby is 3 months and is under the 50th percentile. 3 month clothing fits him perfectly. But 3 months from this company is up to 10lbs! He was bigger than that at 1 month. This footie is the same size as his newborn sized clothes. Be sure to check the weights on their size chart before ordering!
