Big Brother Diploma (with stickers)

Has someone in your area become a big brother? That should certainly be celebrated, because a big brother is super important! He can help to teach and show the baby all new things. Sing a song together for the baby, choose clothes or bathe together, for example. Have the big brother stick a sticker about what he can or has already done, so that he eventually has a whole 'big brother diploma' full. Wow, super handsome! Poster in A4 format, thick paper including stickers.
