Mine are a little further apart - 2.5 years and 3 weeks old - and the toddler is such a good little helper. She gets me the puke cloth (and wipes the baby whether he needs it or not), rocks the bouncer when he's grumpy, tells me when he's awake in his bed, hands me nappies and wipes when I'm changing him, and generally gets right in his face when he's eating saying "baby's eating boobies!" and pats him and is generally just super cute and helpful

I had a much larger age gap between the other two, and an older child with a very different personality and this time it is so much better.
