Hi my 16 month old boy's only comfort item is a bottle. The bottle doesn't have to contain anything, it can be empty, but if he's tired or anxious it calms him. If he had his way he would hold in his mouth 24/7. I've been trying to reduce how much he has it, by just giving at nap times and bedtimes but he can he generally grizzly when he doesn't have it. I'm concerned for speech development and his teeth potentially being pushed out by constant use if this continues. Is this an issue, or should i just chill out and let him have it as much as he wants and he will grow out of eventually?
