Baby girl wet diapers 😟

I just had my daughter 5days ago and im still learning so please bare with me lol. Are there any tips or tricks from keeping the pee and/or poop from coming out of the back of the diaper (towards her back). I always put the diaper on right and its tight enough but the pee always seems to slide out the back. I feel like im doing something wrong 🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔
