What size would I start out with for a nine month old, who is pretty skinny?

The covers are one size, so they should fit. I didn't start using them until my chunky child was 6 mo. The prefolds (I think) are kind of small. I still used them, but also bought more Gerber ones from the store because they were bigger and fit better.

I would recommend a small. My son is 9 and 90lbs and the small fit him snug. We recently move up to a medium which provide more room.

Our son is 9yrs old,4'6'' and the size 14 is a little big but the suit sizes do run a bit small,,,,,,, I'd probably grab the next size up !!!!

I'm 5'9 150 lbs and I got a small. I have enough room to move around comfortably. It really depends on how he wants it to fit. If he wants a bigger fit, go with the medium. If he wants something a little more fitting, go with the small. You can't go wrong with either.

It might be a little big right now, but she'll grow into it. I got one for my daughter last spring when she turned 9. She was about 4'6".

Depends on the size of your child. Mine was a chunk at 11 months (but tall!) and this would not have worked - see my review on June 23, 2012. We also wanted a softer material (ended up going with neoprene) for a child that age. Even if my daughter had been slimmer I would want a softer material with a V-neck.

Well, my Shih Tze I ordered this for is a very skinny 7-8 lb'er. And the XL fits her perfectly & snug. I consider her kind of a minature. This nighty has stretch to it, but would fit your baby ok, even if a little big. To be safe, the Large would fit for sure, but could be on the small side. I'd try the Large & go from there.

Hi Debra, I purchased a size 10 and my son is 9 years old with a slightly smaller build...so I would probably go with the next size up which is I believe a 12. Hope this helps. Good luck. Celia

Seems a little large for my "infant". I can still put it on my skinny 2 year old, but my 4 month old is a bit small. I think 6-12+ months is a good range, right when you're starting to feed some baby food.

I put them on my 7 month old, she's in the 100% for height and they fit so I think they would fit a 9 month old.

I would get the small, my 9 year old is 4'9" and wears a size 12 pant and the large size of these fit him well. I do have to say I sent these pants back, though, the pads are very thin and seem to offer little in the way of protection from any substantial impact. I went with an Under Armour pant for this season and have been happy with Nike in the past as well.

Basing it off of my now 155 lb daughter, I would say get the 110 kb-158 lb size. Yes, you want them to be able to grow into them, but if they are too big and inflexible, they won't be any fun at all.

I would recommend the 6-9 month. Our little girl is 5 1/2 months old and 15.6 lbs and her 3-6 month sleep suit is getting snug. I'll be buying a 6-9 month suit for her soon. At least your little guy will be able to grow into it if it's a little loose at first but I think it would work perfectly!

A small would fit a 9 or ten year old at best. I'm a large and ima pretty big kid 5'10 ,230lbs so id say if the child is less then 190 I'd get him the small

It possibly could fit newborns, however they would be bulky. There is a chance a newborns legs could be a bit skinny, my son was 8lbs 10oz at birth and still needed newborn covers even though onesize covers said they started at 8lbs.

My son was the same when we bought ours and we found 6-9 to be a good fit. He is almost 6 months now and he still fits but it is more like capris and the neck line goes low.

The right size is 00 if the child is skinny, otherwise buy size 0 it will last another 2-3 years. My daughter was size 1 at the age 6-7, she is tall but very slim.
