MIL question....

I have been married for 2.5 years and 20 weeks pregnant.. When we first told my in laws they were very excited, now they barely ask even when they know I went to see the doctor... My parents have been helping us since day one, my mom even comes over and helps with the cleaning, with the dog. We have been fixing our older house and redoing the nursery and my dad has been working on it every night after work! My in laws know all this and never asked once if they could help with anything, not that I expect them to do anything but it would be nice to at least being asked... My MIL comes to visit here and there, she hasn't got anything for the baby yet, not that she has to, but even when she visited us last she made us go to toys r us to get presents for her other grandchildren... I just don't understand.. Are my hormones driving me insane? M I overreacting? Or something is really going on?
