Struggling & juggling

I don't know why but I appear to be struggling recently, it's like I am juggling with too many balls and they are all falling down around me (who am I kidding I can't even juggle with 2 balls)!

Sam is being quite difficult at the moment, not sure if its a spurt, or teething or combination of the two, but he can be so grumpy and won't happily play. He won't sleep in his crib during the day, and only has long sleeps when in the pushchair/car. I think that it is probably due to me walking about a lot to playgroups/preschool/friends most days so it is what he is most used to. He has also been waking most nights again, some nights I have been getting by on just 4 hours sleep.

Having 4 hours sleep is really taking it's toll on me, sleep deprivation really puts strain on the body! I have been getting awfully painful headaches the last week or so, which is something I very rarely suffer with. I am snappy and tearful because of it, and I don't like to be like that, especially around the children.

I have been taking it out on James too, when Sam wakes in the night and he's fast asleep next to me it's hard not to feel slightly bitter and jealous, but I can't ask him to help out, he works two jobs and is always shattered himself.

Because Sam has been quite demanding I haven't been able to give Alex the attention he needs and deserves, we haven't played much, we have done no messy play or baking and I want to, but I just don't have the energy or time.

Any free time I do have is to do the washing up/cooking/loading washing machine and sorting out washing, usually with one or two screaming/upset boys in the background which is stressful in itself.

I am hoping this is just a stage and we get back to being a better healthier routine again, Sam's routine has well and truly gone out the window which has thrown everything else up in the air too-the state our house is in is awful and embarrassing, housework needs doing everywhere!

How do you better manage your time between children/housework/cooking meals/having fun? I'd love to know any tricks that help you juggle everything and get everything running a bit smoother!
