I got my son older a Scuttle Bug for his first birthday, he could use it even though he couldn't walk. He didn't end up using it much but he is autistic which we didn't know at the time and doesn't do ride ons/bikes/scooters anything like that.
This is my younger son's Christmas and birthday lists if they help. Thomas is one on Jan 31st.
