I understand how irratating he must be but you cant breK XMAs. A tip I heard somewhere, might have been on here actually was to say for everytime you are naughty santa has taken away a present and replaced it with a brussel sprout, chuck a few sprouts in the stocking and they will wonder what they would have got.
O please don't do that, agree with dita he will remember it the rest of his life it may put such a shadow over the years to come. You sound exhausted, if you haven't already got some presents try to get a few things today it is not too late yet. There will be plenty of other times to discuss behaviour, maybe something to start addressing after X-mas with a reward chart system.
Hi OP - re the waking in tge night I just wanted to say my ds, who will be four in two weeks, has been waking every nght since he was 3.5. I know it's hard, tiring and annoying but it s a very common developmental stage. He may have started having nightmares - can you find out if that's tge case and try to reassure him? that's what happened with ds combined with changes such as me being pg and potty training. In rhe past two weeks ds has actually had quite a lot of nights where he's slept through so I'm hoping this might be light at the end of the tunnel. Good luck with it.
It may help to take them to bathroom say at 12.00h (I do that with dd, she will be asleep, I put her on loo, hold her, wipe her, put back in bed still asleep). I found that she had bad dreams and woke up very distressed if I did not do this. My grandma always said that a full bladder can result in young children having nightmares, not sure if it is true or not, but when dd had nightmares a few times in a row, we resorted to this and it has worked so far.
