I'm dying here!! Please help!! My twin girls Evelyn and Charlotte are 23 months old, one month early, and have been sleeping through the night for over a year. They have one two hour nap and sleep at night 11-13 hours. Unfortunately, this week Charlotte got sick with a poopy virus and now won't sleep. When we originally sleep trained them, going in to check on them just riled them up and made them cry much worse and longer, so we ended up doing full cry it out. It was a good fit then, but it isn't working now. She won't take a nap at all, crying the whole nap time. Then, at night, she cries until we go get her and then falls asleep on me. Then, she wakes up once or twice in the night as well. One night I let her sleep with me and for the past few days, I've been able to transfer her to her bed once she's asleep, but I'm worried that I'm giving her bad sleep habits. Should I be doing this because she's sick? How do I get her back on track when she's better? How long is too long to let her cry? Advice appreciated!!
