Toddler descending into spiral of over-tiredness! What approach to get him back on track?

[oysterpots]

Went on holiday last week, didn't think it was hugely disruptive but sleep routine has turned to shit as a result.

DS (21mo) taking over an hour to get to sleep despite being exhausted, woke 4 times last night, we're knackered, he's knackered. He was yawning an hour after he woke up today.

Seems to go to sleep sooner if we cuddle him to sleep.

So, my question is:

Is it better to cuddle him to sleep so he's getting the sleep he needs, then deal with the cuddling when he's no longer over-tired?

OR

If I do that am I making a rod for my own back by becoming a prop that he won't sleep without?

Am not into CC.

What should I do?

Try doing the whole bedtime routine 30 mins earlier than normal and offering him more naps earlier in the day, so if he gets up at 7am and is yawning at 8.15am put him back to bed, he will catch up

Try not to get into a settling routine now that you don't want to be doing in 6 months is a good guide, everyone has differing views in what works for them and what they couldn't abide.

No rod, do what's necessary to get sleep, then alter the routine when everything else is back to normal. The older they get, the easier it is to implement changes in routine.

Ok, will try. Thanks. zzzzz.....
