DD is 12 weeks old and very hard to put to sleep! She's had dark rings around her eyes this week so I know she's exhausted but it's really hard to get her to nap in the day or to put her to bed in the evening. We tried "crying down" last night and she fell asleep after about an hour and 10 minutes but I found it horrendous and am very teary and emotional today. DH wantes to try it for a week to see if it helps but I find it so hard. Any tips? Might this work? Also not even sure if we're doing it right - we do bedtime routine including lullabies then leave her, just going in every 3 minutes to rub her tummy but usually that doesn't stop her crying. I find it heart-breaking but DH says it's for her own good.... I don't know if I can face it again. Anyone tried this method?
