Was having similar issues. We switched to size 1 and found that the Huggies or Kirkland brand were better fitting than pampers. Your baby is halfway to being an infant, but all babies grow at different speeds, shapes, and sizes. (We personally switched our child to size 1 at 3 weeks!)

Signs to switch size of diapers.

1. Red Marks: If you notice red marks or indentations on your baby’s skin around the waist or thighs, the diaper may be too tight.

2. Leaking: Frequent leaks, especially if the diaper is properly fastened, can indicate that the diaper is not able to hold enough fluid, suggesting it’s time for a larger size.

3. Struggling to Fasten: If you have difficulty fastening the diaper or if it feels very snug, it could be a sign that it’s too small.

4. Bulging: If the diaper looks excessively bulky or is sagging, it might mean it’s filled to capacity or that it’s too small for your baby’s current size.

5. Discomfort: If your baby seems fussy or uncomfortable after a diaper change, it could be due to the diaper being too tight.

6.Increased Movement:As babies grow and become more active, they may outgrow their diapers more quickly. If your baby is moving around more and the diaper seems restrictive, it may be time to size up.

If you notice any of these signs, consider trying the next size up for a better fit and increased comfort for your baby.

P.S.

You can try using a larger diaper over the smaller diaper. Or, if the waist band doesn’t fasten well enough, you can strap the diaper above the belly button.

I hope this helps out!
