Hey OP, I also couldn't read your post without replying.....so sorry you're going through this rough patch, but from what I've read and in my personal opinion, you are doing a fantastic job! Don't be so hard on yourself hun. I struggle with a 6 month old, ONE child, so I take my hat off to you with two little ones!! I totally agree with amali baby, your DD is probably just after your attention & adjusting to the new bub and going through that 'stage of testing the waters' (I have several friends and most of them went through a similar thing to you with their toddlers around the same age) & your DS is definitely picking up on your stress. When I'm stressed, I have one fussy, grumpy baby on my hands!! Big hugs hun, and I hope it gets better for you soon. Don't worry, when the dust settles, you will be thinking no. 3!!!!! GL and take care hun.

B xx
