Sleeping advice needed

Laura

My daughter is almost 8 months old she spent the first 5 months sleeping fantastically but now she is waking 4 to 8 times a night I haven't been getting her out of her cot but have been soothing her with at least one bottle and lots of sips of water I feel exhausted is this a phase? Or is there something I need to be doing? I tried controlled crying for one night! But I couldn't bare to hear her scream like that she was breaking her little heart
