Mine loved sitting next to a huge box and taking a toy at a time, looking carefully, putting it on the ground next to her and then taking the next toy. She could sit like this almost an hour alone. She did the same thing with all the drawers we had in the house. I also placed her books on the bottom shelf in her room so she crawled there and read every single one of them. She could sit quietly in her room for 30min looking at her books. I miss those times she was such an easy baby, could concentrate on anything for a long time smile She is still quite easy but is talking constantly and needs me to sit next to her playing. As an baby she also loved these wall stickers I had in her room. She took them off and put back on the wall. Same thing with fridge magnets, then she crawled around the house trying if the magnets would stick on different surfaces like the stickers do.

I second swimming and playgrounds. She went to daycare and enjoyed sitting with her friends and changing toys between each others. Do you give him finger food? DD really liked when she started feeding herself at that age. At the daycare they also build tunnels and tents for the babies to crawl in and soft stairs made pillows to practice cross motor skills.
