How much sleep for an 8 month old??

[didsnbump]

My ds most of the time sleeps 12 hours at night, and up till this week was having between 2-3 hours in the day. He did self settles well at night and in the day, but the last week he refuses to sleep in the day in his cot and is refusing sleep even when really tired. The last two days i have resorted to putting him to sleep in his buggy, but he is awake for about 6 hours before i get him to sleep.

Now im ok if this is how its going to be but he is tired and grumpy for a good couple of hours before and i struggle to get his lunch into him??

Ds went through spells where he fought sleep and I ended up walking through the p-ing rain, swearing under my breath, lol!
It may be that this is a phase and you just need to keep encouraging his naps as he sounds like he needs them.

Could he be over-tired by the time you put him down? He could be growing and be tired or be using more energy getting mobile?

I think he is over tired but it dont seem to matter what time i try to put him down he refuses to sleep in his cot. He just gets all upset and worked up. He will then go down in his buggy indoors, but i dont wanna to get into this habit.

Please anyone experience the same and how did you get it back to how it was???

Is he teething or under the weather? That might have something to do with it. Hopefully just a phase. Sorry I don't have any more constructive advice.
