Im well and truly exhausted and lost my 3yr old sleeps well as she loves routine but wakes at 2am and dosnt go back til 5.Shes frustrated most of the tine causing her to bite where she cant tell me things or her sister gets in her way,nothing distracts her shes become dependent on specific songs on utube if u don't get them right she gets angry, i play with her to give her attention. im trying my best but feel like I'm failing.Any advice would be great.
