Frustrated Mama

My 3 week old is so hard to read! For the first couple weeks he consistently ate, then diaper change, then sleep. It was like clockwork. The past couple days he hasn’t taken his usual 2-3 hour naps! I feel like he barely sleeps because I’m getting no sleep! The past couple days when he cries I know it’s not due to hunger or diaper change (because I do that first). I burp him, I try rocking him, etc. What worked today was holding him against my chest but if I do that he gets to sleep and Mama doesn’t. Any suggestions? Lol. Motherhood is definitely challenging but I love the little guy so much 💙
