Most parents do not have a three month summer vacation; they must work during the day. (compound sentence) This means that their child or children might be left alone for the entire day. With some children, this is not a problem, but with some others, this could wreck havoc. Day care can cost an arm and a leg (synecdoche), and some parents do not have adequate day care options, especially for three months during the summer. All year school breaks are more spread out and are normally set around the holidays, when it might be easier for parents to find someone to watch their child, or even to take a few days off work.
