I'm really struggling with my toddler and my 8 week old baby. DS is 28 months, was a little angel until DD arrived. Now hes become aggressive and hyperactive. He kicks, hits and pinches us both. I use time out if he is aggressive and try to remain calm but be firm and say he cannot do this and it hurts. He takes absolutely no notice. Usually this happens when I'm feeding her or changing her, he becomes incredibly excitable and just cannot be controlled and when told no, resorts to aggression. DD has got big feeding issues and cows milk allergy, reflux and barely drinks, hates to be put down so is a very demanding baby too. I now have to take DD upstairs to feed her so she isn't hit by her brother. I put her in travel cot downstairs but DS can climb into it so I'm constantly on guard. Today while I was feeding her upstairs for 5 minutes, I came downstairs and DS had pooed in the kitchen and smeared poo all over the sofa and his leg and was eating it. I honestly don't know where this behaviour has come from or what I'm doing wrong. I'm trying to meet up with friends and their toddlers to occupy DS and burn energy and also am thinking of increasing his days at nursery because I feel like the interaction is good for him. Any other ideas?
