Will his crib fit in your room or switching it to a toddler bed is a good idea. My son had bad eczema so we let him stay on our bed until he got too big at 2. We moved him to a toddler bed and placed it next to ours. When he was 3, my daughter was born. I moved to another bed so we wouldn't disturb my husband's sleep (he works long hours and needs his rest). My son wanted to stay with me so the 3 of us were on the big bed until he turned 4. I transitioned him back to his toddler bed by my side until he broke his bed by jumping on it. Then we moved him into his own room. My daughter has been on the bed ever since. I don't have the heart to kick her out.
I'd say when he does wake up in the middle of the night, train him to sleep on the floor next to your bed so all of you can get a good night of sleep. Just use the mattress pad from the crib or roll out a sleeping bag or use a thick blanket. Babies and toddlers rarely sleep through the night. They have semi awake phases. My kids used to use their feet or hands to feel for me when they wake up in the middle of the night. I call them feelers. They feel secure when they know someone is next to them.
Every child is different when they start speaking. My son didn't say his first word until he was 14 months and he didn't string his sentences together until he was 2 1/2. But he understood everything. To communicate, he'd point too and say "ah" or "uh." Don't worry. As long as his pediatrician isn't concerned and doesn't think he needs speech therapy and is developing fine, all is well. My daughter spoke early. She said a 6 word sentence at 9 months. Now my son won't stop talking. He's 13.
We are unconventional. We didn't let our kids cry it out. We let them sleep when they need it and eat when they are hungry. I think they turned out okay. On their first day of preschool and Kindergarten, they happily left my side and ran to their teachers. I was the only one that cried. My brother used the cry it out method on his kids and they turned out okay as well.
Music is fundamentally important for the development of the brain. Studies have shown that playing an instrument and learning music pieces the only exercise that works out every part of the brain so it's like fireworks going on in there. Great article Gracey! So go into a routine and play his favorite music cd or mp3 before bedtime and let him play with toddler musical toys.
Good luck on the move and hopefully his sleep habits will get better and all of you will get good sleep!
