DD was dry at nights about 12 months from when she was day time trained. Reading this there is such a massive variation! We took DD to the toilet before bed and then before we went to bed for several months then she kinda just clicked with it. Like others have said, I think there is a long time before you need to look into it further.
DS is 5, he has had one dry night and Im pretty sure that was a fluke anyway. He has been day trained from around 2.5 years. I was a very late night trainer so its no surprise really.
DS1 was night dry from 4. Night of his 4th birthday he said didnt need nappy now as he was a big boy, and we have 2 accidents in over a year!!. He did not day train till 3 years 7 months!!
DS2 he day trained at 3 years 1 month and is not night trained or anywhere near it his nappy in morning is so heavy and full, (does not poo in toilet yet grrr another thread!)
Night TT is a developmental change and some kids can be 7 and beyond. Most drs wont even invesitigate until 7.
