B.C.
My daughter is 12 months and 2 weeks old. She is defiantly going through the same thing. She always wants me to hold her and when I try to put her down she just screams. She always wants me right by her side at all time of the day. She doesn't do this to daddy, just me. This is what you call seperation anxiety. It peeks the highest between 12 to 15 months of age. Beleive me, I have read book after book on this topic and I beleive this is exactly what it is. Read about it. The information will be very helpful.
