It's fine, but worth bearing in mind that many children not dry at night at 5 are unlikely to be dry at night by 7 so you may want to seek referral to an enuresis clinic by the time they are 6-6.5 if still wet (many have huge waiting lists).
A lot of it is developmental, and also related to the adequate production of vasopressin which usually kicks in around aged 3 but can be much later.
Things you can do to help:
Encourage plenty of fluids in the daytime, eg between 0700 and 1700. If a child doesn't drink enough during the day whilst at school they are then thirsty when they get in and have the bulk of their fluids later in the day, meaning increased urine production after bedtime.
Remember milk is a food as well as a drink and takes longer to digest, so is converted to urine later. Avoid milk, hot chocolate etc at bedtime.
Do the 3Ts at bedtime - toilet, teeth, toilet so that the bladder is completely emptied.
Lifting isn't recommended as you are reinforcing the 'wee whilst you are asleep' message. Of course it can enable a dry bed but won't actually contribute to achieving night time dryness. If you need to take a child to the loo after their bedtime/before you go to bed then make sure you have fully woken them.
