My daughters been sleeping through the night since she was about 6 weeks old but for the past week she's been waking me up two to three times through the night . I feel like I have a newborn again!! she's also been a lot more clingy, wants to nurse and be carried all the time. Any other moms going through this with their 4 or 5 month old?
