I don't think I am stimulating my LO enough

I am just so exhausted enough already feeding him, changing him, putting him to sleep and washing his bottles. I have no desire nor energy to make time to stimulate him. He is one month old and he is fussier than ever. He wakes up every 2-3hrs sometimes every hour. When my husband gets home he plays with the baby but during the day keeping him alive is more than enough work for me 😢
