12 vs 18 vs 24 Month Baby Clothes

baby clothes and toys

Your baby grows incredibly quickly in the first year. At times, it may feel like they’re only wearing clothes for a few weeks before they’re moving on to a bigger size. However once they reach the 18-24 month mark, the growth rate tends to slow down a bit and this is reflected in clothing sizes. The weight range on baby clothing labels becomes a little smaller and you have other options, such as toddler clothes which may suit your baby if they are very mobile and not crawling any more.

In this article, let’s take a look at the difference between 12, 18 and 24 month sizes. When should you switch between them? Should you consider toddler clothes instead? Here’s a quick overview on the difference between the 3 sizes before we look at this topic in more detail.

  • The 12 month size is for 20-24lb babies who are between 28-30 inches in height.
  • The 18 month size is for babies who weigh between 24-28lb and are 30-32” in height.
  • The 24 month clothing size is for 28-30lb babies who are 32-34” tall.

What size does a 1 year old wear?

Not all 1 year old babies are the same shape and size so it can really vary. Some babies who are larger than average may need 18 month or even 24 month size clothing. Moreover, if your baby is already walking quite well, you might want to consider 1T size clothing as this will make it easier for them to move around. However, your little one may still be content in 9-12 month or 6-12 month sizes if they are a little smaller than average.

As a rule of thumb, always go by the size of your baby rather than what age the labels say you should be using.

You will know which retailer stocks the best fitting clothes for your baby after trying out a few items.

When you should start looking at toddler size clothing?

Once your baby is up and about and fairly mobile, then you can start looking at toddler size clothing. This can be anytime from 12 months onwards, but it’s more likely from 18-24 months. This style of clothing will have longer legs and less space around the waist area, as your baby slowly becomes potty trained and has no need for a diaper. In terms of appearance, this clothing will look suitable for a small child, rather than a baby.

Is 1T the same as 12 month clothing?

Although you won’t find the 1T size in many retailers, it may be an option for you if your baby is an early bloomer in terms of walking and mobility. 1T sizes (but usually 2T) are the first in the toddler range of clothing (going up to 4T or 5T) and they are little bigger than 12 month baby clothes, with longer sleeves and pants and a thinner waistline. Here is a detailed comparison between 1T and 12 month clothes.
