You actually need to increase your blood pressuer a little.  Mine was very low with my last baby, to the point where I was constantly feeling light headed and dizzy, even when sitting down.  If your blood pressure is too low, it can affect your baby too.

By the way, since when have you been pregnant?  I know I'm not on here much these days, but how did I miss that?

I agree with the last post.  When I was pregnant and exhausted with little ones, used to lock myself in one of their rooms and take a nap.  They played contentedly for a few hours in there with me with toys.  Some days it was all I could manage!!  You have to do what you have to do!

Could you play in another area of the hosue, for instance his bedroom where the kitchen and dining room arent' so close? Otherwise, investing in a baby gate may help! This will allow you to relax more and not have to worry if your little one is going to venture into the kitchen..Otherwise, if a baby gate is out of the question maybe installing cabinet licks so your little one can't open the cabinets in the kitchen and dining room will help!

I wish you the best and hope you feel better
