My 11 week old has started sleeping so well at night it started at 7.5 hours and his nappy was fine I’d change it after his bottle.

He’s gone up every night by 30mins and after the 8hr sleep his nappies are leaking… iv tried different brands, it’s not major leak just a little bit. Do I size up a nappy? He swamps the bigger sizes though but I’m thinking it will hold more wee?

Any advice welcome, but I’m not going to wake him to change him. I enjoyed my 9 hours last night! (If he was soaking or whatever obviously I would)
