My DD is 14 months old and every day especially on lockdown is a minute to minute struggle. She has an attention span of about 90 seconds (not exaggerating), clings to me and whinges for most of the day, shouts, cries, pulls my hair. Without baby groups etc to distract and occupy her (she won't watch TV and has LOADS of toys) this is pure hell. Is this normal? DH thinks she might have ADHD or something.
