My 6 week old baby refuses to be put down. After breastfeeding, she either will settle in my arms (rarely) or sometimes struggle and cry. When I put her down, she cries and fidgets all the time. I don't know what's wrong. I had burped her, diaper is clean, she's well not feverish. Tried singing song to her, talking to her. Tried walking her around the house, she was quiet for 1-2 mins before she got bored and struggled again. I'm so worn out. Any recommendation on how to soothe baby or how to let baby settles?
