Yaaaay for Sophie!!! And I hear ya on the age recommendations - and it's hard not to get swept away, when you know you want a tailored list, but toys are everywhere!
DS is 14 months now, and the best toys we have are hands down wooden blocks and trucks. He has alphabet blocks and building blocks (arches, cylinders, etc.) that he adores. A wooden cement truck is a favorite, as is his wooden block train (if she isn't super into vehicles, per se, I have seen some cute wooden rolling animals).
Other than that, he continues to love anything salvaged from the recycling bin (paper towel tubes, glass/plastic bottles, cereal boxes, almond milk jugs, etc.). I think when he was about the age of your DD, he really got into taking caps and lids on and off of things - including child-proof caps - and other fine motor stuff, like putting holly berries or dry spaghetti into narrow-necked bottles, sorting small things in bowls, etc.
Sensory bottles are also a cool idea for the wee ones (that still mouth things!) - you can put food coloring in water and add oil to the bottle - they can shake it up and watch it separate. You can add glitter or a thousand different things - just glue the caps on if she is good at getting them off! You can google it for lots of ideas.
Musical instruments are huge in this house - any kind of simple drum, the Melissa and Doug band in a box, or any homemade instrument (rice in a bottle, wooden spoons, pots and pans, beans in a box taped shut - some of those need alot of supervision, but easy to make). DS is a dancing machine these days, constantly requesting the iPod, but he's always loved music and will make it with anything.
DS loves to "sort" the laundry and his cloth diapers - and pull everything out of our drawers - so maybe a pile of playsilks or small clothes in a basket for that purpose. He's been really into "helping" with household chores like vacuuming, washing dishes, etc. for a while now, but you've still got a bit for that - it's great though, no toys needed!
A wool felt ball would be nice, too - light and soft and easy to handle. I do notice the natural materials get played with a ton more in this house! And tons and tons of books, of course - including some lift-the-flap books - DS loved those at that age.
