Good quality and thickness fit well width wise. I find they are a little on the smaller side length wise due to needing to allow for nappy room. I’m now using the biggest size available (2-3 yrs) but not so in all other clothing purchased (12-18 mths generally) I’m not sure what options there would be now if child grows a lot over next few months. My child is on the small scale too. Note the last pack I bought 1.5/2yrs were identical size to previous ones 12-18 only the thickness was greater with less stretch in material.
