Oh Hun, so sorry to hear you and DD are having a rough time with care...

My son cried for the 1st few weeks as i did also... its normal for them to be upset but my son wasnt crying all day long... Maybe you need to tal;k to her and let her know you'll be back to pick her up, maybe start by only leaving her for 1/2 day until she starts to get used to it???

Maybe stay there with her for few times so she thinks its a safe place to be ??/
