@ejfan291 You didn't mention a budget, so I included the approximate prices for each item, based on memory.
We got our baby a Pikler triangle + ramp for his birthday, and he loved it. He used it constantly until he got more comfortable walking, but he still uses it occasionally now. (Costway brand from Target on sale for $100.)
He got a play kitchen for Christmas, and he still uses that every day. I think he'll continue to use it for a long time because he keeps finding different ways to use it. (Teamson Kids from Maisonette $180, plus wooden fruits and veggies and stainless pots and pans $40)
We already had a Nugget (we bought it while I was pregnant), and while that's probably the most versatile baby item we have, and I would highly recommend getting one, I don't know how great of a gift it would be for a one year old. ($230)
We used it a ton when he was learning to crawl, my husband and I have both slept on it comfortably, and it makes a great pre-bedtime reading spot. I'm sure it'll also be great for fort building when my toddler is ready for that, but right now, it takes a lot of effort to use it as a toy, which isn't exactly conducive to independent play.
