Diaper question

My son is 10 days old! We been using the Huggies diapers on him, however sometimes he will go pee but it’s all in his back, makes his clothes wet and bassinet wet. He only weighs about 8 lbs or so right now so he’s still in newborn diapers. Is there a way for us to not have this issue and he just goes pee in his diaper? I am a ftm so I have no idea. Please let me know if you know! Thank you!
