He's one month old and I started "shh/pat" today. Worked great in the morning, and since then he's been waking up every time I put him down, after 5-15 minutes. I've spent the day putting him to sleep, and he's woken up within a few minutes almost every time. He's been tired all day! (good sleeping leads to more good sleep, and the opposite.) what am I doing wrong? HELP!
