When did..

Okay, so I KNOW you’re not supposed to compare kids, because every kid is different. But when did YOURS start speaking/walking/feeding themselves? My son can’t say any legitimate words regularly yet (he would have just been a year old per his due date) and while he CAN walk, he chooses not to do it solo (but furniture surfs CONSTANTLY). He also only has two items he’ll feed himself— I wasn’t worried and wasn’t comparing, but my husband and I got into it the other day because his co-workers kids are ahead of him, and he feels like our boy is falling behind. Now I’m worried he is falling more and more behind.. I don’t know what’s “normal” :(
