Asshat, I don't know who you're think you're fooling by talking about subscriber increase. It may say 611K subscribers under the channel name but you're still only averaging 25,000 to (occasionally) 71,000 views per vlog. That is significantly less than 611,000 subscribers. You're not even averaging one fourth of your total subscriber count. I've said it before but it's still true, it's nothing to be proud about, to brag about and it doesn't mean shit when your average views are much much less than your total sub count.
It does nothing more than generate clicks and interest when you say that you don't know if Abbie will ever speak (vocally). You did say that the older she gets, the less likely it is. Which is the truth. So, points for that. But I think you've known for a long time that Abbie will never speak vocally.
It's also bullshit how you talk about Abbie using her device or sign language for communicating when you don't do simple things like using sign language WITH her, you just bark at her to do a particular sign here or there. You never engage in conversation using sign language. When you were having your little heart to heart w. her about what does she dream about, you didn't have her device ready with her and knew she she couldn't answer beyond what she did.
As far as sensory seeking, I've also said it before and I'll say it again, if her sensory needs were met on a regular basis, it'd be a lot less likely she'd have these "wild" sensory seeking days where she's getting into everything, making messes and destroying stuff. Rather than waiting until she has these "super stimmy" days before you take action, do something to meet her sensory needs every day. And yes Priscilla, that would mean having toys and sensory objects around the house in view and not hidden away in boxes in a closet or cupboard. You need to get over it. Asshat, you say you think there needs to be more studies done in how sensory issues affect the brain. You can start by not ignoring her needs and waiting until things boil over before doing something about it.
