18month soaked through

[Franktank19]

The past week or so, when I get my baby after his 10hrs sleep he is soaking!
Nothing has changed, he still has a bottle at bedtime and I use the same brand of nappies I have always used? Why is this suddenly happening? Any tips?

Stop the bedtime bottle it makes a massive difference to night time urine output and at that age it's non essential. Milk from a cup before bed is more suitable.

Go up a size in nappies
