I got my twin boys the two roller coaster sets on the bottom shelf for their 5th birthday in November. By Christmas all they wanted was more Lego. My wife and I decided that we would keep giving them sets as long they kept building them. We had no idea it would get to this point after only 4 months. It has been a great hobby to get into with them, but our bank account needs a break. submitted by /u/peteypabz88 [link] [comments]
