My pup is now 6 months old and while she was little I didn't mind playing with her at night to tire her out for bed, but now I would like some time to myself again !
It would be really nice if I could get her to settle from say 9-10pm before a pre bed wee. If I locked her away she would cry and wake the children but if I ignore her she brings toys to us, then proceeds to lick us and then nibbles to get attention !
Any advice would be great.

She doesn't need physical tiring out for bed but mental, that works quicker.

She will be confused if the routine she has been used to suddenly changes, she is still very much a pup and won't understand why her previous antics are no longer acceptable, this is why I don't allow behaviour that I won't be happy with for the rest of their lives, somethings can be funny initially, nipping,licking,jumping up,begging for human food and constant attention seeking but they soon wear thin so it is time at the start to stop this and teach the pup to amuse themselves at certain times of the day, human meal times for example and to praise and reward them for doing it well.

Using extra special treats to keep them occupied in their bed/crate so any interest in you is lost at that time,
bones, stuffed/frozen kongs or chicken wings have worked here in the past, now any new additions take their clues from the rest of the pack so when I say bed they will follow the rest till I indicate they can come out.

Hope she settles soon.

If you don't want to play with her, ignore her.  She might bring you more toys and lick and nibble you more at first (extinction burst) but if you ignore that, she should give up (behaviour should extinguish).  But it will get worse before it gets better and it's extra important you ignore when it gets worse or you'll be rewarding that more intense pestering of you and get more of that instead!

Thank you.
