SAHM and Pregnant

Hi there so I'm a stay at home mom my son is a year and a half. I am pregnant with #2 and am becoming so lazy all I do is sit on the couch feed my son and nap when he does. I'm so bored and don't wanna clean or do anything. I keep up on the dishes and that's about it. I get random Spurs of energy at random times but not for very long. I think some if it has to do with just being SO bored I miss working and seeing people everyday. So I get into a rut and can't shake it. Hate feeling this way.
