I didn't let my son go to nursery until he was 3 . My husband and I even worked around each other because I didn't want him to go. I hated the fact that I wouldn't know what he was doing? Would he feel like I had abandoned him? I also had another son by this time who was 6 months old.
One day I put his name down, I loved the nursery and put him in 3 hours a day. He's a September baby and wouldn't go to school until he was 5. He needed the interaction with other children. By the time I had got him there, walked home, put my other son down for a nap, cleaned it was time to collect him. It did us both a favor, when he was back in the afternoon, I could dedicate my time to him. I didn't have to clean up, everything was done.
My second son when to the same nursery and is now at school, my daughter is still at that nursery she's 4 next week. They all love going back to see their old key workers.
Good luck, whatever decision you make xx
