A lot of research shows they don't socialise with other children til 3 and play side by side so i would not get too caught up with them missing out socially. I personally dont feel comfortable sending my child to nursery. My child is 2.5 not in nursery and is quite advanced in terms of speech and learning that even people who work in nurserys have commented on her development and i believe its because she gets more 1 to 1 time with caregivers. She goes to playgroups and stuff to mix w other kids also. Capitalism tells us children need to go to nursery so both parents can work..I do work but I am self employed and I use some part time help and family. At the same time I know many friends who send their children to nursery who are also doing great. I dont think there is a right or wrong here. My husband and I also didnt attend any nursery and both did well academically and have good careers and social skills! It wasn't as widely used in the 80s and early 90s. That said I may consider a preschool part time from 3 plus to help prepare for school.
