My baby girl is doing the same thing at night time and I can understand how tiring it is! She is 7 months old and the last week or so she has been harder to settle to sleep, especially at night.

Tonight it took me about an hour to get her to sleep in her cot even though she was really tired. It is like she is starting to realise that she is by herself in her room. As soon as I pick her up she falls asleep. The last couple of nights I have started to put one of my t-shirts tucked into the side of the cot. That way she can still feel close to me! It does seem to help so maybe you could try that!
