It surprises a lot of parents how much ground a kid can lose in eight or ten weeks of no lessons. A child who was floating confidently and swimming ten feet unassisted in May can come back in August tentative again, needing a coach's hand for support they didn't need before.
Kids don't forget the mechanics so much as lose the comfort that made the mechanics work. Swimming at this age relies heavily on confidence, a kid who isn't scared moves better, breathes better, floats better. A long break lets that confidence slip even when the muscle memory is mostly intact.
One lesson every three or four weeks during a break, even a single one, tends to be enough to keep a child from backsliding all the way. It's a lot cheaper in time and money than restarting from scratch, and coaches can tell almost immediately in a maintenance lesson whether a skill needs a full refresher or just a quick reminder.
If your family is heading into a slower season, ask about a reduced-frequency maintenance schedule rather than stopping lessons outright.
Keep your child's progress from slipping during a break.
