Its normal you will feel mean but your not hun , its called independence and we all have to show our Lo's how to go about it , in her eyes she dose not know what your doing , so when you do something you think is wrong she wont know or care ..she may get fussy but shes old enough to start learning about limits ..
yes mums are always there but we need some " us" time too for our sanity.. when she comfort sucks can you distract her with a toy or a cookie (finger foods )
