5 signs your baby’s diaper is too small

5 signs your baby’s diaper is too small


When you finally get to bring home your brand new bundle of joy, it’s hard to imagine them ever growing out of their adorably tiny newborn diaper size. 

It comes as a surprise to most of us how quickly they graduate to size 2 with no signs of slowing down. 

Size guidelines on diapers overlap by quite a bit and it can sometimes be difficult to know what diaper size might fit baby best. 

So how do you know when baby’s bumper is due an upgrade? 

We recommend looking out for these 5 signs that your baby’s diaper is a size too small. 


1) Leaking 

Does your diaper not last as long as it used to between changes or do you suddenly experience frequent leaks? Moving up usually resolves this because bigger diaper sizes offer increased absorbency. If your baby develops a rash overnight, this might also be due to a saturated diaper and the wetness being close to the skin.

2) Red marks around tummy and thighs 

Are you noticing red marks on their tummy where the waistband of the diaper sits or on their thighs around the diaper’s leg cuffs? Even in the absence of marks, if little one seems uncomfortable in their nappy or suddenly sweats around the waistband, trying a diaper size up is also a good idea.

3) Poor fit 

While a diaper should fit snugly around waist and legs, you want a loose fit at the front and back. Also make sure the diaper is big enough to cover the lower part of baby’s tummy, to just below the belly button. Finally, double check baby’s buttocks are completely covered.


4) Tabs don’t close comfortably to the centre of the diaper waistband 

Are you having to pull the diaper side tabs to get them to close? Are they sitting quite far apart on baby’s tummy when fastened? As soon as you are unable to fasten them without any pulling or wiggling, give the next diaper size up a go.


5) Mobility 

When baby starts to walk and crawl, or is starting to become interested in potty, some parents prefer switching to diaper pants. These will make for extra-quick changes and allow little one to pull them down themselves when getting used to potty. A great way to make toddlers feel more confident and boost their independence.
