I can't get anything done! My son is a little over 6 months now and never stays happy for longer than 5 minutes in a bumbo, jumper, high chair, literally anything we have that he can be on his own in. He freaks out after just a few minutes. Even when I'm right next to him! Even if I have him in the high chair playing with toys while I stand right there and make myself food! Then the second I take him out... he's fine 99% of the time. Anyone else having this problem?
