My longest two for settling were 4 months and 7 months and yes, they are long, long months! It is stressful and exhausting and I feel your pain! I just transitioned two new babies and now they are about 16 & 17 months old and have settled in finally. It's awesome when they finally settle in. I wish you best of luck and calming thoughts and relaxing, restful, healing evenings so you can keep your sanity. BREATHE!!!!!!!
