Как удивить старшего ребенка на baby shower? Идеи для праздника в честь второго малыша, чтобы не обделить вниманием старшего брата

I am throwing a surprise baby shower for my sister who is having her second baby in October (baby shower is this sunday). I couldn't do one for her first baby as she had him in the first lockdown. Anyway, my nephew is almost 2. What can i do for him at the shower that acknowledges he will be a big brother and makes a fuss of him too?xx
