Oh Mum of many big hugs to you. I know where you are and when you are in it its so hard to see the light when you are not even sure you are in a tunnel with an end! I have 3 preschoolers still and homeschool the other 4 so I really need to work sanity breaks into my day. I aim for small things like all the children (not matter how old) have 1 hour quiet time after lunch. This sometimes gives me time to catch up on job or simply crash in exhaustion! Driving my kids to activites I sometimes zone out and put on my music and ignore them, not really they usually laugh at me singing all the words to songs they don't know and bopping away!! I will get a dvd and so chocolate (when hubby is away) and switch off the brain in the evening. I have all my family in NZ so a nice long, long distance phone call is always a help and escape. Of course escaping into Belly Belly is another option and there are always wonderful supportive people in here. Hang in there girl and I know its so hard being pg as well but very soon you will have a precious little bub to cuddle and somehow you will do it just because you are a fantastic mum and love your children.
