When my daughter hit around 4 months old she all the sudden began HATING the car. At that point, due to insufficient milk supply, we were having to supplement and when she would spit up in the car I chalked it up to formula intolerance or overfeeding. However, we eventually weaned her off bottles completely and got my supply up to the point where we are no longer supplementing. She never spits up anymore, but will still occasionally get sick in the car. I recently began considering the possibility that she has motion sickness. At first we also thought it was the carseat, but we have two different seats which she equally cries in. It's so bad that now when I try to put her in the seat she's strong enough to arch her back and fight me to not go in it. It breaks my heart to have to restrain her in it.
Obviously, since she's still only 7 months old we are still rear facing and she is in the backseat of the car. Sometimes putting the window down will help her, but often that isn't enough. What can I do to help alleviate the car sickness? I have tried looking for a bracelet but nothing I've found is for under 2 years old. What do you recommend for infants who hate the car and for infant car sickness?
