Looking for a big sis for our 2 boys

Hi you can call me Liz. We are always welcoming for those who love spending time with kids. We have a 5 years old son. He is fluent in Turkish, English and just started to learn German. He is a playful one, he loves his legos, riding bike, swimming and playing outdoors. He is going to a kindergarten during school-days so you will have plenty of time to yourself to discover, learn, travel etc. Basically we need a big sis for him to play with and learn a few hours a day.
