Calm before the storm? 😰

My baby is 6 weeks old and he's honestly such a dream. He only cries when he's hungry or tired, doesn't mind being put down to play by himself, he sleeps a 7-9 hour stretch every night, naps about 4 times a day and is generally just an easy baby which I LOVE since I'm finding motherhood hard to adjust to and I'm not sure how I'd cope if he was a difficult baby. I keep hearing that it gets harder at about 6 weeks and I'm shitting myself that he's going to wake up one day and go crazy 😁 do all babies have sleep regressions and become sooky at around 6 weeks? I'm dreading it 😫 hahaha
