Can anyone help?! My 5 yr old daughter has always been a good sleeper but recently gets very upset when I leave her in her room. She wants me to stay upstairs near her room, not actually in it but close.She constantly calls out to check if I am still upstairs and this is stopping her falling asleep. She obviously anxious and however much I reassure her it's always the same...she has a drink, light,door open etc. anyone got any bright ideas?!
