Hello- I have 3 children 6 years, 4 years and 22 months now.. I always kind of wondered about that too. But I learned it is so important for them to play alone. They learn independence, discovery time and time to be alone. You are not a bad mom, but I would say give hime some time in the swing, exersaucer etc.. too.. also tummy time. We took a lot of walks at that age, trips to the park, perhaps he might be ready for the swing soon, look at the ducks in the pond, etc. discover the world, it';s a great innocent time for them to learn eveything around them., also i did story time just to give them time around other babies, my house was always so quiet when I just had my first, we played alot of music in the house, read books, use this time to relax and enjoy, and in between feedings and naps etc. good luck and you are doing a great job I am sure of it.
