Hi A., I have an 11 month old and she is my first as well. I have worked with children of all ages for years and I believe strongly in their ability to understand more then we give them credit for. I have taught my daughter sign language (just the basics- more, please, all done, etc) so she can communicate with me even if she doesn't have all the words yet. I also don't let her whine at me (that is my biggest pet peeve) I tell her "no whining- tell me what you want. She now points and says "That." sometimes it takes us a few seconds to find what "that" is, but it helps her understand that she can communicate without whining! I also have been working hard on making sure she is balanced with her development- she spends time playing by her self, sitting with me on the couch reading books while I read mine (we are up to 30 minutes now!) playing with other children, walking the furniture/crawling around the living room with her toys and a more structured time we call "Blanket Time" This is time she spends with Mommy or Daddy playing on a blanket with a few toys and books. This is important because it teaches boundaries. She has to stay on the blanket during this time and she does! She loves it, I know that she will be able to be left alone to play and stay on the blanket at some point and that will come in handy when we are out at other's homes, in the park, etc.
I also have taught her to understand "no" and "don't touch" by telling her and if she doesn't listen she gets a tap on the hand. It doesn't happen often because she is a fast learner and we have been consistent with our approach. She is also praised for good listening- I can say "Isabella, come here please" and she comes right away- this gets a big round of applause! On the off chance that she doesn't come I tell her "You need to listen" and go get her and bring her to where I called her. This is very rare though.
As far as sleeping through the night- mine has trouble too sometimes. I know at about 9 months they sometimes go through a separation anxiety and just need reassurance that you are still there but we handled it and things are better now. In the night if she did wake up and cry I would wait a few minutes to see if she could put her self back to sleep, if not I would usually find her standing up at the end of the crib wanting to be picked up- I stopped doing it because she is never going to learn to go back to sleep on her own if I did. I would simply tell her "it is night night time and she needs to lay down and go to sleep." I help her find her Nuk and lay her down, put the blanket over her, rub her back for a second and then she falls back to sleep. Each time takes less and less time and each night it happens less and less. What she is learning is that I am still there if she needs me but she needs to go to sleep by her self. I also pay attention to her diaper- we usually have a diaper change at some point in the night or early morning and also hunger- sometimes if she doesn't eat well during the day she needs a few oz at night. But those are minimal issues.
I am sure to some this may seem too structured or high expectations but children are very intelligent and are capable of learning more then just how to whine to get what they want. They learn what we teach them- if we respond to their misbehavior by giving in then they learn that it is OK to do that. If we are consistent with our developmentally appropriate expectations then we will be amazed at how well they understand and how quickly they learn.
I hope this helps and if you want to talk more or get together some time I am right in Cranston and always looking for play dates!
