Help with 1 year nap issues

[19066264wow]

My 1 year was napping at 10am and 2:30pm for an hour each but recently refuses the second nap. Since it's so long until bedtime I've slowly pushed 1st map to 11:30 but he still only sleeps 1 hour and is exhausted by mid afternoon. His room is dark with white noise and have tried him in a buggy too but still wont have 2and nap. Any suggestions?

Will he sleep in a sling, if you go for a walk? But now you've pushed the first nap later, it might not work anyway, or he might only sleep in the late afternoon, and then not sleep easily at bedtime.

But how old is he anyway (in months)? It's common for 14-18 month olds to drop their second nap.
