Ana,
The early skipped kids (DS 9 skipped 2nd when he was 7 and DS 5 skipped K when he was 5) had no troubles skipping. They were definitely able to do the work and fit in better with the older kids. No attention or behavior issues (at school). They were fluent readers. Much easier earlier on than for my oldest who skipped 5th. DS 9 broke his arm 3 times and was writing delayed because of it (he used his left to write, then switched, still has poor handwriting, but can type fast
We're always considering 2nd skip for DS 9.
