The answer is “no”. In fact the complete opposite, daycare is actually good for a child. From studies we’ve researched when children are not placed into a school setting until 4 years old and up they have a harder time adjusting. They have a greater chance of having social anxiety. Children who start childcare at an early age tend to adapt very quickly to become much more social and interactive with both students and teachers. If you don’t believe it, ask a kindergarten teacher.
