Aldi’s Nappies - Size 1 / Size 2

Morning ladies! My little girl is almost 6 weeks old, she’s 9lbs 10 and still wearing size 1 Mamia Aldi’s Nappies. Not sure when to change to size 2. I tried one on her a little while ago, seemed to fit the waist but not the bum. Her size ones get really sodden sometimes though.

When did you move up a size? Thanks in advance xx
