This is going to be an unpopular opinion, but not everything has to be super expensive wood toys for your child to get enrichment from them. I've actually had a terrible time with expensive magnetic wood blocks (Tegu Blocks) not holding up well. The same goes for fancy wood rainbows and other similar toys. Think paint flacking off, accidental injury when playing with them, etc.

My now 21-month-old LOVES magnatiles (tons of excellent imaginative play, plastic and magnets), mega building blocks (plastic), her dolly, the stroller for her dolly (not wood, from target), a tea set (plastic) that came with a stuffed animal, crayons, her kitchen equipment (she helps cook with us), and her books.

As for wood toys, I've had great luck with the Melissa and Doug line (she loves the puzzles), Amazon basics has a line too, and keeping an eye out for sales at the local expensive baby store.

When she was your little's age, her favorite was an obnoxious plastic ring set (sassy rings I believe) that was gifted from her grandma, Fisher-Price wooden/plastic toys (this line may be defunct now, but they hold up amazingly well if you can find them, I found them at Ollie's Bargain Outlet and on Amazon really cheap), a cheap large mirror I set up for her (think back to school sales), and random household objects (spoons, kleenex boxes, amazon/shoe boxes, hats, scarfs, tennis balls...random stuff).

I really think the magic of Montessori is giving your child space to be creative and explore their world without overwhelming them with flashy, light-up noisy things. Additionally, our world in 2022 includes lots of bright colors and plastic. I get that Montessori is a whole aesthetic, but I truly believe if you're giving your child the freedom to grow and explore their world at their pace, you're on the right track.
