It's a normal nap time for their age - annoying as it is! As Rebekah says, early lunch/brunch and then something for when they wake up
That’s a normal time for 1 nap! Our boy started about 11:30 and the last week or so had gone down about 12! We do snack about 10 before nap then lunch after nap, he has lunch before nap at nursery though
Is that one nap or two? If one, that sounds quite normal i think, I generally try and keep mine up until 11.30. Depending on wake time do lunch 11/11.30 then nap and then a substantial snack once he wakes up
