First time I needed to assist with a molt.

So my Psalmopoeus Pulcher sling molted a few months back and I noticed that it had developed a small bump on it's rump. The bump didn't seem to be causing a problem so I just decided to wait and see if it disappeared on the next molt. That was today which surprised me because we did not see any signs that it was coming. When the little one was done it flipped back over but we couldn't get a good look to see if the bump was gone so we decided to try to gently pull the molt out because it seemed to be sitting on tip of our little one. Well when we pulled on the molt we realized it was actually still stuck, right about the point where that bump was. We decided the best thing to do was to try to help. We just lost our Ephebopus cyanognathus sling to a bad molt last month and it might have survived had we been able to help (we were gone so didn't see it until too late). Well we just held the piece of molt and this little sling seemed to understand and pulled itself out. I still see a bit of a bump but it's much smaller. I'm a little worried that the stress of being disturbed while molting might cause it to die (it's about 3/4 inches right now). But after seeing my other baby die from a molt that easily pulled off with tweezers I thought this was the better option. Fingers crossed that this little one makes it through the night, when we left the room it was running around it's enclosure a bit perturbed by the disruption but seemed to be moving freely.
