Christmas ideas for 3 month old

My baby girl will be about 3 months at Christmas (give or take a bit depending on when she decides to come) and I’m a FTM, never had to buy gifts for a baby before. What types of things would you suggest as Christmas gifts and even stocking stuffers for a 3 month old? Not looking to spend too much since she’ll be so young and she’s the first grandchild on both sides so she’ll get plenty from them as well:)

Edit: so she will definitely be getting Christmas pajamas (tradition from both our families) and then I was thinking maybe getting a floor gym/play mat since we don’t have one yet. However, I’m not sure what age those are good for. Will she be too old at 3 months or just right?
