Gosh there's so many out there.
Firstly I wouldn't recommend going all out on expensive stuff, they really do get lost, broken filthy.
I suggest looking on nuby website, got all my stuff from there.
You would need, a simple simple sippy cup and I got another one that's open for when they've got used to the idea.
A couple of plastic cup suction bowls
Loads of spoons, they go everywhere haha. There all same really, some are chunky for baby to hold but didn't work for mine really.
A cup suction plate.
Lots of little jars, if your making your own.
Nibbler with net - there good at beggining for tastes and no risk of choking
Bibs lots of them.
A mat to put on floor they are messy buggers haha.
That's it to be honest, I wouldn't bother wasting money it goes so quick, and I didn't use stuff I bought.
High chair again I wouldn't go all out, mine was from aldi was great but now at 11 month I put him on a portable one at the table 🤷♀️. All do same thing.
Good luck it's so fun but my walls, radiators now need painting 🤣
