Deferral decision

[Babybrain26]

Our son will be 4 years and 4 months starting school. He has a slight speech delay and has just had grommets inserted this week. His older brother (currently in p1) is awaiting asd assessment but is sailing through school. Our youngest us rather different, academics don't motivate him at all, hes been on numbers but that's it. The ot has said he has weak core muscles, a sensory seeker but can function and fidgety. Hes quite social bur sensitive and has made a good group of friends that will all be going to p1 together. (He would be the only one deferring) husband doesn’t want to defer but im not sure that's the right decision on the long run for him. I just don't want to do the wrong thing by him . It's so hard. Any advice?

Personally I’d let him go with friends. Being around dc of his own age and older should help with language. Staying with younger dc not so much. Is he doing well in other ways?

He might also like YR and learning - it’s not the same as nursery. I think I’d send him to school as he doesn’t seem behind socially and probably would notice all his friends going and not him.

Which country and how common is defferal for his age?

@TheNightingalesStarling NI and not that common yet as its fairly new here and difficult to get a second nursery year (we're self funding).
