What actually happened was that No 2 has carried on as if nothing has happened (though she's pleased with her new 'doll'). No attention seeking, no playing up, no jealousy.
No 1 (8 years old) was more problematic - feeling misplaced, superfluous, and a little misunderstood. This surprised us as he was absolutely fine with the birth of number 2. What was new to him was feelings of jealousy for the tiny one's affection - he'll happily cuddle the baby for hours, but sometimes, his little sister has to have a go.
At the time of writing (No 1 is now 1 year old), he has settled down, but this may just be how the pieces settled, rather than any change in him - No 2 tired of baby before he did and he mostly gets her to himself.
Meanwhile, No 1 and No 2 have started bickering. This may be more to do with No 2 starting school and being in approximately the same stage of life as big brother, rather than his underling.
