I have a a gorgeous 4.5 month old baby who didn't make a peep for the first 3.5 months, never cried, slept well, ate well. She recently had her 3rd injections and ever since then its like I have a different baby.She wont let me put her down during the day, or night. She cries non stop. She will only fall asleep on or beside me and as soon as I put her in her bed she wakes up. She is also not eating as well as she was. We have tried to let her cry herself to sleep but she doesn't stop, and works herself up into quite a state! Anyone gone thru this? Or any tips on how to make it better? We are at our wits end!!!!!!
