We don't particularly mind repainting a few months/a year down the line. Our son is 3 and really into science (I mean the child science things you can buy) or age appropriate science videos, so we thought would be nice to do a science theme, plus I have lots of things that would fit! The best colour for the walls is this darker pink, it matches really well with the potion on the duvet set. My mum has asked why we would purposely paint it pink
