I'm seriously sitting here about to cry over a tracker system that my boyfriend told me no to... I don't think he gets it, I'm not too picky over things but I think this is one o should be able to get, HIS child has out me through hell compared to my other two and I'm only asking for this one thing... He makes me want to smack him telling me I'm childish and I need to get over it because it's just a car seat and stroller... Just let me be spoiled this ONE time damn...
