awwww you have got a lot on your plate. Don't beat your self up over it, your doing the best you can.

On the sleep thing though.. Does she have a day sleep still? Maybe its time to cut that out if she does? Iain is 2 (just today <3 ) & if he sleeps inthe day I can forget a decent bed time. So no sleep for him during the day. All of my kids have been the same. By the time they are 18/20 months day sleeps stuff up bed time for us.

Also maybe on nights you really need to study Shell could take over bed time? Jazzy will get use to it. Maybe you could go tot he local macca's for an hour & study there? or hang back at work an hour to study before heading home?

Huugs, things will get better.
