I'm a mother of 3 children - Zoe (age 3), Rocky (18 months) and Lucy (3 weeks) and have successfully done Babywise with all! I think the hardest part of BW is the beginning - many people get frustrated with find that optimal wake time periodand tend to give up. If you are struggling - hang in there!! It will be worth it! I swear by BW, all 3 of my kids are completely different but all are excellent eaters/sleepers. My son (Rocky) even had emergent heart surgery at a week old and we were in and out of the hospital up until he was 4 months old. We still tried to do BW as much as possible and it even worked in that situation. Thanks for your blog! I have used it as a guide with all 3 and so thankful for you for documenting your journey!
