why do i feel like im all alone? i ask for help from my boys ages 6 and 7 almost 7 and 8 and my husband and they dont help me at all with any of the house work. i end up doing it all and then i pay for it later on with alot of cramping. and we also have so much to fix around the place like the siding of our trailer a leaky sink in the kitchen just to name a few of the many things and who has to do it may i ask me thats who we still need to get the crib up yet he will be here in 8 to 10 weeks
