Chester - 12 months old wellcheck

Chester is growing very well. Today he took 4 vaccines during his 12-month wellcheck. Poor baby...he had to go through the process longer than it supposed to because the nurse noticed the needle on the 4th shot was broken that she had to run out to get a new one. Chester cried so loud, but he stopped as soon as mommy held him in my arms. I never worried about the delay of his teething, but both sides of grandparents were so concerned that I decided to raise the issue to Dr. Peng. She advised no need to worry until he's 15-month. The more immediate concern is that he still can't sleep through the night on his own. As Dr. Peng recommends, there's no other way except to let him cry through with no limit on time. Based on other parents' experience that it will only take 4 days to a week, he would be able to learn. Cry through with NO LIMIT ON TIME! Owen has no problem sleeping through Chester's crying...even Haley can still sleep without waking up when the doors are closed. No one seems to bother except ME. Sigh! Chester...please grow out from waking up every 2 hours at night. Mommy need more rest so I can be a better person during the day. Don't make me go to the extreme resort!
