Lessons are one on one and scheduled 4 times per week, 10 minutes per lesson, Monday through Thursday.
Infants 6 months to 13 months (or not walking) learn a short recreational swim and then a roll back to float. This takes approximately 12 to 16 lessons. Toddlers 13 months (or walking) to 4 years will learn the entire Swim~Float~Swim sequence. This takes approximately 16 to 24 lessons or 4 to 6 weeks, depending on the age and abilities of the child. Most children finish in 6 weeks. Of course, there are always exceptions because some children take longer while others are quicker at the learning process, so it depends on the child.
