My nearly 4yo DS has speech delay and, we're pretty sure, ASD (he's under assessment atm).
I gave birth to our DD three weeks ago and we always expected DS to ignore his sister for a while, but not to be terrified of her! He gets very upset when she cries (understandable) but today she brushed him with her foot while he was sat next to me and he absolutely freaked out.
I've been v careful not to push the baby onto DS or force him to interact with her, but I do talk to DS about his sister, and try and explain what I'm doing when I care for her 'I'm changing her nappy now' etc.
Has anybody else been through this? What helped? Or do I just carry on being patient and hoping he warms to her?
