Leaking

[hxnn]

My baby's only just 12 weeks. He currently uses size 2 nappies but every night he sleep 5-6 hours, and when he wakes up he's soaked even his sleep suit is soaked cause he's leaking out the nappy. I did try a size 3 and they are far to big for him.
We use pampers nappies so I know they are decent and not cheap nappies

Anyone have any ideas how I can stop them leaking during the night or if there's a night nappy that he can wear this young? As I'm worried he will get a rash where he is so wet when he wakes up.

Different nappies. Pampers always leaked for us, I really rate Aldi Mamia nappies or Ocado own brand. Never had an issue with either.

I second the Aldi nappies. Price doesn't always equal quality IME. Pampers leaked for my DS so we tried other brands and Aldi nappies were the only ones that didn't. With DD who is 11 weeks we've just gone straight for Aldi nappies, no problems with them up to now and there have been some mega poops.

You need to try different brands. Each baby has a slightly different shape that will suit some more than others, eg I find Tesco ones are great but Sainsbury's ones often leak

Whenever my baby pooped in pampers it used to seep through to her vest and clothes but now changed to Lidl and this doesn't happen.

Pampers all ways leaked for us, Tesco's nappies are amazing and less than half the price. I only discovered them after a neighbour gave us some their DC had grown out of, it was a revelation!
