Problem with bootstrap field alignment

I'm facing a problem, which I can not solve. Home What I want seems to be simple, to align the small field well below the written amount, I did some tests with methods I saw by the master google , but the field insists on being caught in the middle.

<!-- Caixa Quantidade -->
    <div class="row">
        <div class="col-md-2">
            <form id="formExemplo" data-toggle="validator" role="form">
                <div class="form-group">
                    <label for="textNome" class="control-label"></label>
                    <input id="textNome" class="form-control"
                           placeholder="" type="text">
                </div>
            </form>
        </div>
    </div>
<!-- Fim caixa Quantidade -->
