When my little girl was just 5 weeks old, she began to sleep through the night. You're wondering, "How did she know it was 5 weeks precisely?" Well, she was born on a Sunday. The Saturday night before her 5 week "birthday" my husband was on baby duty. I woke up realizing I must have been exhausted because I didn't hear her once. I then peeked over my husband to look at the video monitor, which woke him. I said when did she get up, he said she didn't. I immediately jumped up in panic thinking something was wrong. Now we do use the Baby Sense V, so I knew if it did not detect movement for a short period of time, the alarm would sound. No alarms. I went in and she was soundly sleeping. I immediately begin going into panic that she must be woken up and fed because she couldn't sleep that long. It was nearly 9 hours. My husband did what I asked and, for the next week, I woke her every night after about 6 hours of sleep. We then went to the doctor and he asked why I would wake her. I said she needed to eat. He assured me that if she was hungry she would let me know. So with that, I let her sleep.
Initially, it was for about 9.5 hours then it slowly progressed to 12-13 hours of sleep, which she consistently does. She's now almost 11 months. We don't have any problems with waking up in the middle of the night unless something is wrong.
You will find tons of resources about assisting an infant to sleep. Here's what I have found works for her and seems to work for others who have tried these techniques.
First, before your baby is born, I highly recommend purchasing
The Happiest Baby on the Block. You can go to www.happiestbaby.com to order it. I recommend the DVD and CD. The swaddle blanket is a must have. The one that they offer is the one my sister-in-law used and she swears by it. I liked the Summer Infant Swaddle Me Blanket. It was simple to use - it seemed easier than the blanket on Dr. Karp's website. Again, my sister-in-law swore by the other blanket. BOTTOM LINE: You need a swaddle blanket. Babies seem more secure in them and they seem to enjoy being in that cuddled position.
Now, for the DVD, it explains some techniques to calm. We found the techniques to be HIGHLY effective. We could always calm her easily using the techniques. Even before we were able to get a bottle. She was like a crazed lunatic when she became hungry, and she went from not hungry to hungry in the matter of two seconds. However, she liked her milk warm, which took time.
The CD - or lifesaver as we like to call it. She loves the hair dryer sound. Some people argue that white noise is not good. The doctor said it will not effect her hearing unless we have it extremely loud and close to her - we don't do either. I have found that white noise works. She HATES car rides and it makes life so much easier when she has her hair dryer playing. She doesn't cry and she's more comfortable. I tried different noises - the CD has five - but have found that the hair dryer works best for her.
So, how did I get my infant to sleep through the night at 5 weeks? I used the swaddle blanket, Happiest Baby DVD and CD - Dr. Karp's method. It has truly worked. One other thing that I have found very helpful is
Healthy Sleep Habits, Happy Child by Marc Weissbluth. This is my guide for every stage. It has guided me when I was having trouble with naps. It has answered questions and given me additional techniques. These are MUST-HAVES, in my opinion, to help your infant sleep.
