Let me tell you about my eldest when he was 2. He was a good talker, so we didn't suffer too much with tantrums, and I do think that makes a bit difference.
He was however, painfully shy and clingy. He never wanted to play with other kids, he just watched them and maybe copied what they had been doing when the coast was clear.
Since he was born we went to various activities. I was also a child who never did anything and didn't want the same for him. I also found it easier to be out of the house for a good portion of the day.
Wherever we went he was basically mute. He looked away and buried his head in me if someone spoke to him. If we went to playgroup he liked the free play but didn't like doing songs at the end. Was too scared to pick up an instrument from the basket. Never sang, clapped, danced, while all the other kids were having a ball.
At home or the park, in the woods he was as happy as Larry. Chatty and laughing. Unless a neighbour tried to speak to him, then his head was buried. I was a bit worried to be honest, but obviously he was still very young and some people are just shy I guess. He was fine with people he knew very well and in smaller groups. Often when we were out in an unfamiliar place it was too overwhelming and he wanted to be carried. A safety/comfort thing.
Then lock down struck. He was 2.5. All the parks closed, soft play, cafes, everything, as you know. No play groups, no swimming, nothing. One walk a day and crucial car journeys only.
We had to spend our time just playing, just the two of us. We played with water and sand in the garden, we planted things, fed the birds. We read and read and read. Talked and talked. Did puzzles, played imagination games like cafes and shops, built train tracks, made ramps, sang songs. Had horsey rides and tickles and bouncing on the bed. We would walk through the fields and down to the canal. Throw sticks in, look for ladybirds, collect buckets of stones and leaves, press flowers. Come home and make some food and do the laundry together. Get the hose out and wash the car.
It was a long old slog to be fair! But do you know, he actually thrived. Just slowing down the pace of life, forgetting all those "enriching" groups that I thought were so important, were really not. Quality time spent with his immediate family were what he needed. He started talking to the neighbours first, they were really surprised. Then when we could see friends again he just talked and talked and was happy to play with their kids. He just blossomed in that first year and was like a completely different child. We went back to one of old groups and he loved chewing the ears off the adults there. I started to worry he was too talkative then!
Anyway, the point is, there's something between sitting in front of the tele all day and having every day structured going here there and everywhere. He knows what he likes and what he doesn't like. He might not be able to say the words yet, but he is communicating to you. Listen to him. Dial it back, connect with him, give him all your attention and take him places the two of you can just have a pleasant time together. That's all a 2 year old needs.
