Sudden change in sleeping behaviour

My baby is going 10 MTHS in 2 weeks time. Recently, she will cries very badly (shouting and screaming) when put in bed, and wanting us to carry(both daytime nap n night) And very difficult to sleep back when she woke up midnight for milk. In the past, she used to lie down by herself with her comfy blanket and sucking thumb. After milk, she just dose off herself. Not sure of why the sudden change. Any similar experience?
