I am really struggling to feed Cally. She is heavy and I struggle to hold her, especially if she is doing her usual trick of pushing against me with her feet. I usually feed her lying down but that isn't really practical when we are out (though it would be fun lol). I never really had this problem with Seren as she was smaller then Cally and by the time she was the weight Cally is now she was sitting up great and able to support herself, Cally can sit up but not for that long. I usually hold her in a cradle hold with her body going across my body supported by the arm on the same side as what she is feeding from if that makes any sense.
