Baby stocking fillers?

[Palmface]

We have a 1 month old baby who needs nothing, but I'm looking for ideas of things to put in her stocking so that my older kids (preschooler and school aged) won't think Santa has forgotten her.

Stocking - over the fireplace, the older kids are getting sweets, a few little plastic toys and an orange. What on earth do I put in there for a baby who only eats breastmilk...?!

Sack - at the end of their bed with proper presents from Santa. I've got the baby some books and clothes so that should be OK.

Help!

Dummies, teethers, Teddy / comforter, socks (everybody needs socks), book, hat, rubber duck / bath toy.

Basically anything that baby needs.
I'd put something under the tree too even if it's a hand me down baby toy.

Stuff that will be useful in a month or 2, nice sippy cup, bowl & spoon. Socks (my kids get socks in their stocking every year) rubber duck for the bath, stacking cups.

I wrapped up baby wipes, baby shampoo, a rattle etc when my ds1 was a baby

I put in cup, bowl and spoon (for when older), socks, little book,

Little toys bibs socks dummy little book

I’m confused that Santa leaves two lots of stuff in your house? Surely Santa leaves only the stocking?

But anyway - I did a little one for my son when he was 6 weeks. I put in a chewy teether, a baby toothbrush (some sort of toiletry is tradition in my family) a nice bead grabbing/teething toy, something else I can’t remember. Definitely think about things for the future not just for now.

My dd was 1 week old for her 1st Christmas so I wrapped:
Clothes
Toys for her to use as she got older (tethers, shaker, sensory bits)
A 1st Christmas bauble
A cuddly jellycat elf

Dummies
Teething toy
Rattle
Cuddly
Christmas socks
Christmas sleep suit
Christmas decoration
Musical crank box
Hat
Scratch mits
Bubble bath
Baby talc
Baby lotion
Wooden letters spelling name to put on bedroom door

We do the stocking and sack thing as well, except in house the stocking is upstairs and the sack is downstairs.

I'd go with some sensory toys. So a peekaboo scarf, rainbow coloured ribbons, bubbles, jingle bells, that kind of thing.

Then practical bits like socks, bubble bath etc

A little book, plastic baby spoons, sippy cup, Christmas socks, bath toy, chocolate lolly (that you can eat), pair of baby shoes in a bigger size, baby bubble bath, hair clips (if girl), teething toy
