My little one is so grumpy. She won't sleep and if she does its with alot of hard work and not for very long. Shes 3 months old. Ive tried putting her in her cot and she just screams ive tried puttingher in hercot once shes fallen asleep for her to go longer she wakes.Ive tried letting her nap in various places downstairs nothing works. She then cant take her bottle as shes so tired and grumpy and just screams all day even at baby groups etc.
