DS is doing well in PT and making progress, but he still feels really behind--especially when I do the worst thing and compare him to other babies, which I know I should NOT do but it's hard!

I am in a very small January 14 moms group on Facebook, and out of 12 of us, I think at least 3/4 of them have posted pics of their babies pulling up to stand and complaining about how mobile they're getting that they can't keep up, etc. DS still doesn't even shimmy on his tummy, and definitely still won't even try to bear weight on his legs unless he's forced to during PT or home exercises.
I
know that he's doing fine, and that it will come in time and that frankly I should be
glad he's not running around the house causing trouble yet! But sometimes I get a little demoralized and worried that he's not advancing sooner. Anyone else working on a motor delay feeling a little bummy and want to commiserate?

Its really tough to not compare but like PP said comparison is the their of joy. Instead what I have found helpful is to celebrate each milestone you do hit regardless of when it is.
While my friends were bragging about their LOs saying the ABCs I talked about how over the moon I was over Ben saying mama. Who cares if it took him until age two to do it, the point was he DID it.
It's exciting when he finally starts to do something other babies have been doing for months, and frustrating when the physical therapist is disappointed in what he isn't doing yet. He's making progress, and I know that's the important thing.
Sometimes I'm able to relax and tell myself he's on the slow side and that's ok, after all someone has to be on the other side of average. Other days I worry about every little thing he is/isn't doing. What if he isn't just on the slower end? What if something is wrong we haven't recognized yet? Why did he do that weird thing earlier? Etc., etc., etc. I've spent many a night googling and then freaking out internally about everything that could potentially be wrong with him. It's maddening. As luck would have it, it's often right after I get anxious about lack of progress that he makes some new huge leap and I get to breath easy for a little while. Darn babies!

This is all silly, I know, but I agree that it's so hard not to worry! He has made some big leaps though--I need to just focus on those and keep positive!
