I have this little girl (10 months old) whom I have been looking after for 3 months now. She is still no settled, she cries a lot, everytime I put her on the floor until I pick her again, everytime I put her in the high chair for feeding time, she is ok when in my arms but I cant have her all the time in my arms. Beside her, I have 2 dds (5) and (2) and another little girl, which makes a total of 4 (during holidays). DD (5) became increasely stressed around this little girl because of the crying and even become stressed when this little girl is not here yet, example, Mummy, who are you looking after today ? Me : xxx, hence dd crying...I know it does take some times to settle a baby but the situation is really stressful. I'm really doing my best reg activities, including everyone, try to give everyone a bit one on one time but I'm clearly unsuccesful..This little girl is really affectionnate and cuddly but has a massive anxiety separation...What would you do ?
