Masuki i am going through the same because i am finding it difficult to balance motherhood and my relationship with God, then i heard someone preach that quiet time with God does not mean closing yourself in your room only, it can be when you are shopping, jogging, making dinner, showering, anything done with God in mind is quiet time, after that i relaxed, realised that God is with me no matter what, we don't stop being in a relationship with him because we get busy, He knows, and i say the same to you, every activity done with God in mind is sometimes all we can do.
It gets to a place where when i am watching tv, i go Lord, what do you think of that? i talk to Him all the time because i am tired of praying the same prayer over and over, if i said the same words or started a conversation with my DH the same He would think i am mad, so i figured when i give DD a bath, while she is playing, i sit there with her and go, Lord, she is so beautiful, thank you fro trusting me enough to give her to me, sorry, i could go on,
i don't think i made any sense there.
