My 17 month old baby hasn't passed urine in last night . why

A. Has your child passed urine after waking up in the morning or not that’s a thing because of the child and passed you in the night then that’s a good sign because every parent want the child to be toilet trained that they should not urinate in the bed or a diaper they should urinate in the morning after waking up so this seems fine otherwise if you face any other issue with this thing then please elaborate your question and talk to your doctor
