Feeling sorry for myself...

I live in a different town to my Mum. I came down to stay and look after her after her second operation to remove cancer in her arm. I have my 3 year old and 18 month old with me and am 22 weeks pregnant with baby #3. The last 2 nights I have had no sleep with my 18 month old and today he ended up in hospital. They were about admit him for the night but after a dose of steriods he was cleared to go home (Yay!!)..... then after I get him down for the night (hopefully!) my 3 year old cant stop vomitting so obviously has a bug that is going around. I dont know how much more I can handle with these pregnancy hormones. Hopefully tomorrow is a better day!
