This question already has an answer here:
Im planning a trip from vermont to New York, its about a 4 and a half hour trip and my babygirl is 1 month old. Im just worried she will get overwhelmed at being in the carseat so long, of course I will stop whenever necessary, I breastfeed and dont use bottles yet. Im also worried she will get sick, or her body will be in pain or cramp from the same position so long. Is this a safe trip and what other things should I do to ensure she will be okay??
