My breasts feel empty! Has my milk supply decreased?

Felt the same way before especially when my kid turned older and can eat solid foods already - breast was lumpy, so soft and baby was latching less. Then realised that it did not happened only once therefore felt that it's completely normal - baby poops the same frequency, gains weight and stayed healthy. On my end I tried to be not so stressed about it and let it be. And bear in mind that the supply is directly affected by baby's demands and needs.
