Infant toys recommendations? (10-11 months)

Hi everyone! My sister just had her first in early December - we didn’t get anything for the little one for being born or Christmas. We are going to see them for the first time in early March, flying from the States to Germany. We won’t see her again until she’s 10-11 months. Whatever we get will need to fit in our luggage, though we will have lots of room.

We don’t mind ‘buying in advance’ if something is meant for a six month old, but we want to get her something fun, as my sister and her husband have the baby’s basic needs met.

What do you wish your baby had gotten at this age? Or what did they get that you loved?

Thanks in advance!
