What's the best nappy rash cream?!

[hipbippbop]

DD is nearly 3 and we started potty training about 6 weeks ago when we thought she was ready... thought we mastered it around 3 weeks in. She has a wee on the toilet and very rarely has an accident (accident have only ever been at nursery though).
However over the past week and a half she's been saving her poo for when she's in a nappy overnight. Her bum is red raw, I've been putting sudocrem on it and tried a barrier cream too but they're just not helping.
Just checked on her now and It looks so sore and I've had to do a full bed change.
What cream have you found effective? Previously used honey barrier cream which was great... is metanium good?
Any advice if greatly appreciated!! I just don't want to keep buying lots of creams that aren't rated highly.

I also know I need to solve the root of the problem so any tips on getting her to stop saving her poo's would be fab!
She's still in a cot, and I plan to convert it to the bed soon so will wake her up for wee on the toilet when I go to bed.

Thanks :D

Metanium every time. Tiny amount, very thinly spread as per instructions. Worked every time for us.

100% metanium

I use sudocrem or bepanthen day-to-day and metanium for when the skin is red and sore. I find metanium heals the skin really quickly.

Yep, yellow mentanium.

Metanium is magic - sparingly!

Another vote for yellow metanium!

Yellow metanium 100%

Only downside is that it stains any clothing or fabrics it may get on

Ok thank you all so much!! I'll be stood outside boots in the morning waiting for them to open to get some metanium 😆
