First, for teething, I recommend homeopathic teething tablets. In my experience, they have worked bette than any gel. You can find them at most drugstores. Target carries the Hyland's brand, which I like best. It's in the baby section near the bath products.As far as the sleeping problems go, I feel your pain. I really do. My son didn't sleep through the night until he was 10 months old. He grew very quickly and could never eat enough during the day. He'd eat 2 or 3 jars of baby food at each meal and was taking 36-48 ounces of formula a day. Buy the time he was about 9 months old he was simply in the habit of waking up every few hours, whether he was hungry or not. Nothing would get him to sleep, not even crying it out. What got him sleeping was that he started throwing tantrums at nap time when he was about 10 months old. He wouldn't calm down, so I left him in his crib. (His older sister threw tantrums at this age as well.) I didn't intend on making him cry himself to sleep, but that was the result. After a couple of days he figured out that he was ok in his crib and he started falling asleep on his own and sleeping through the night.My youngest is almost 11 months old. She was 9 months old before she slept through the night. We had to make her cry it out, which was hard for me. But, there was nothing else I could do. At the time, I was very sick and my husband had a broken hand. He couldn't put her to bed, and I couldn't keep from coughing or sniffling long enough to get her to sleep. She cried for about 30 minutes and ever since then she has been a pretty good sleeper. (With the exception of when she was sick and teething.)I was never one to advocate for making a baby cry it out. It always seemed harsh and hurt me too much. But, after three kids, I've learned that they're all different and need different methods for certain things. Crying it out didn't work for my first, sort of worked for my second once he was ready, and definitely worked for my third. I would give it some time before trying the cry it out method. If your baby is legitimately hungry, don't withhold a bottle. My youngest needed a bottle up until a month or so ago. It was hard, but after 3 kids in 4 years, I'm definitely used to interrupted sleep. Now when she wakes up in the middle of the night, I just rock her for a minute and lay her back down and she's fine.If your baby does not seem to need a bottle and won't sleep even in your bed, he may just be used to waking up. Crying it out might help. But, if you aren't comfortable with that, you don't have to do it. I know how hard it is to hear your baby crying and crying. One thing that helped my older two was the LeapFrog puppy pal. They loved theirs and still like to sleep with them. My youngest doesn't seem to care much about hers, but the lullaby music and cuddling with the puppy helped comfort my older two. Other than that, my only advice is to just wait it out. It's normal for babies (and kids and adults) to wake up in the middle of the night. It can take some training for babies to figure out that it's ok to be in their crib alone. Being in a separate room can actually help older babies to comfort themselves. If they are in the same room with you, they will be more upset that you aren't giving them attention. But, some babies just take longer to sleep through the night than others. My oldest slept through the night at 6 weeks, my second took 10 months like I said, and my youngest took 9 months. It just depends on their personality and their body.
