Regulate parent and child parking spaces

As a mother of two young children I am currently juggling car seats and buggies in order to leave my house to get the most simple things done. However, on many occasions I find myself struggling to find adequate parking to safely get my children out of the car, especially in retail destinations, such as supermarkets and retail parks. This is because the destinations either have very little or no spaces available. Regulating the use of the spaces would simply and easily rectify the situation in many cases.
