sahbear - I wait for her to start rubbing her eyes before I even ask if she wants to go to bed, thing is shell fall asleep really quickly if I'm holding her (and she's tired enough) like tonight I was lying down with her on our bed and she was out within about 5-10min but as soon as I tried to transfer and she woke she wad screaming in the cot

HotI - she only has one sleep per day, usually around 2-2.5hrs from around 11am ish. depending on the day. she only had 1 hr at daycare today and was clearly tired and ready for bed.

milka - I don't think skipping the day sleep will work, she seems to actually need it, gets very whingy and unreasonable and constantly yawning and rubbing her eyes if she doesn't get one.
I thought possibly a fear of the dark, but I just don't understand the suddenness of it and why it's only when she's in the cot? she doesn't communicate much though no makes life very hard sometimes. 've tried the teddy and she just chucks it out and the hallway light is always on but it doesn't seem to help with that either :/ she already has a pillow too lol
