the size 6-6x is bigger than the 4T or do they refer to 6 months?

I have researched your question and this is what I've found out. 4T the T stands for toddler and in 6X the X stands for wider version of 6 and maybe a little taller, but not quite a 7 in size. 7's are taller and thinner than 6X. 6X is for larger than Toddlers not 6 months. I hope this helps.

I found them to to true to size. But if he's long you might be better off going with the 6-9 month.

My daughter is also 4 months old and these are a bit big on her, but I figure it's better than being too small bc she can grow into them.

Im size 6 and its fine. But size 4 is quite smaller. It would probably still work, but would also be quite bulky.

I am using size 4 for my 13 month old. 4 is deff fast. 3 is medium. I believe size 2 is the slow one.

My son is the same age and almost exactly the same size as your baby and right now he still fits in the 3-6 month but I think in another month or so I'll being moving up to the 6-9 month. I would get the 6-9 month so you have some room for your baby to grow.

They will be a little big but not TOO big. My nephew is a size 4T and they are just right on him.

Yes. I believe it will fit most 6 month olds. My daughter was almost 8 months when I got her first one. That one broke after a year. The second one she lost when she was two. She's now had her third one for about a year and she's 4.5 years old. She wears it 24-7.

My granddaughter just turned three in January. She is 29 lbs and fits in the size four. The six may be long for him but you can always roll up the sleeves and legs. And he can wear it for two years I would guess.

I bought premium 4x8x4 not infant 4x8x4, but the premium is better fit for my 6 mons baby girl. However, its length is pretty long for her, and it covers all my baby girl's tummy. It will fit when she turns to 8 mons I expect. I just can say that they are the same size, but the premium is thicker, so I expect that I can use it longer than the infant one.

My son is 4 but can fit 3T or 4T and it's large on him. I think it could prob fit till about 6 comfortably.

Our daughter is 26 months and in 2T and they are roomy on her. Her cousin wears a US sz 6/6x at age 4 and she also still wears them! They are short in the sleeves on her though, but she still wears them no problem.

I would do the 3-6 so they last longer. I went up to the larger size for my kids for that reason and I'm glad I did!

Yes, I'd say the same as others, unless you've a huge baby small is a great first size for 0-3 or even 4 depending on the size. But if you're buying them now at 3 months maybe consider only a few small and go a size up for most so they last a bit longer. Though if you're planning on another baby anyway you will need them again anyway.

The size 4-6 should fit him fine! My son wears 5ts and it is a perfect fit! He probably will not be able to wear it after a few months but for now it is a great fit!
