Maybe its not the fact that she is bored,maybe she has gas and it hurts.Car rides are bumpy so it may help her out some but at home she is still which doesn't help it at all.

She's a bit young to get much out of toys. Maybe it is gas. Do you stop mid bottle and burp her? That might help if you don't. Burp her after the bottle as well.

Also, she might be over stimulated. Young babies can only take so much before feeling overwhelmed by their surroundings. Try soft lights, low noise levels ( soft music or white noise, like a fan, dishwasher, etc) and wrapping her snuggly in a blanket - arms tucked in and just rock her in that position.

If your not able to rock her for long, you can try a baby swing, that might help as well.

Thats a good idea! Babys do get overwhelmed after a while,you just have to calm them down.
