Ideas for a 2 year old's birthday party at home

[Notveryxmasy]

DD was born as we went into lockdown and her first birthday was also during a lockdown so this is it! Her second birthday and her first ever party just for her!
Only a small gathering, she'll have 2 friends her age there and her 3 older cousins (6-10). 8 adults.
I've never thrown a party for a small person before so what can I do to make it special for her? And games people can suggest that I can put on that both the older kids and the toddlers will enjoy please?

Balloons
Music in they can dance to
Musical statues - for the older ones the younger ones can just dance

Hide lots of little chocolate coins all over the house and get the older ones to help the younger ones find them. Once they have found them hide them again. We recently did this with a mixed range of children and they loved it.
