Hi,
My DS is 5 months old and currently has 3x naps everyday. The morning and lunch time one in his cot and the afternoon one out in the pushchair. He used to sleep for 45/50 minutes but this has now reduced to 30 minutes. He will sleep for longer, sometmes up to 1 hour 40 minutes in the pushchair if on the move. Very occassionally he'll sleep for longer at lunch time for no apparent reason 
I think he needs to sleep for longer at lunch time as he wakes crying and is grumpy. Whereas he wakes quiet and happy from his morning nap 
I have tried re-settling him at lunch time but he just gets more and more upset so it seems unfair to persevere longer than 10 minutes or so.
Has anyone successfully managed to extend their lo's nap lengths. I'd love to hear people's experiences, tips etc.
I know that I am lucky that DS naps as well as he does but I think he would be so much happier in the afternoons if he could do a proper chunk of sleep (it would also be amazing for me to have a proper amount of free time in the day to rest or catch up on jobs
)
Thanks
