I was a single mom too and sleep issues are different for each kid.
my question is....if he was coming late and you know your daughter needs specific rituals to sleep, then why didn't you start those rituals without him?
My 2 year old goes to bed by 7 or 7:30...she sometimes cries out at night but we don't go into her unless she cries in earnest...some whimpers won't get us down to her room because she cries in her sleep and if we go down to her, it will actually wake her up.
If you are working 16 hours a day, I would imagine your daughter would miss you...maybe spending some quality snuggle time with her instead of making sure she is in her bed at 7pm sharp might go far toward making her feel secure
