I spoke to a number of nappy brands about this and they send me samples and said that all nappies fit slightly different and to try different styles until you find the right one for your child.
We use Pura nappies in the daytime but have switched to the Huggies bedtime nappy pants and 🤞🏻 haven’t had a leak since!
We tried almost all the nappies and still had leaks, then I tried tesco Fred and flo and maybe had 1 or 2 leaks in 8 months. I used little angles from asda with my 1st and they worked great for him, but not this time round for some reason.
Tescos little rascals have been the best for us. They’re on par with pampers price wise so a bit more expensive but that far more absorbent and sturdier. We call them the fancy nappies in our house 🤦♀️ and save them for night and the cheaper ones for during the day. Only disadvantage is that not all Tescos sell them Other things to consider are making sure baby is warm enough at night. Some times a baby will wee more to warm themselves up! If the nappy is completely fully and leaking this might be contributing. Also, not sure if you have a boy or a girl but if you have a boy to make sure his penis is pointing down… we learnt both these lessons the hard way!! My baby is 5month old. Sleeps 10-12 hours without waking or a nappy change and drinks a good 30-36 ounces during the day when he’s awake and since using the little rascals nappies and checking the other things I mentioned we haven’t had a leakage in months
Mama Bear nappies on Amazon are the ONLY nappies my baby hasn't leaked through because she literally wees for Britain....
Try little angels from Asda I've never had a problem with them ☺️
