This is the first time I've posted so please help! DS is 6 months old and until recently was a very lovely, chatty, happy boy (apart from not sleeping terribly well...). Last week he seemed to transform into a very whingey, irritable baby that doesn't smile very much. He's also gone very quiet and not making all the noises that I love! I miss him. Where's he gone? I'm wracked with guilt that it's my fault coz we've been doing a bit of controlled crying. Have I done this to him? I thought it might be teething but apart from constant chewing he's not showing the classic signs of teething. Is this a normal 6 month thing? Will he come back?
Many thanks!
