It's all gone upside down since about three weeks ago when I was due with dc3. He's two weeks old tomorrow and she's still waking early. She doesn't go to bed particularly early (that's usually a dream but hard work there too) and she doesn't have naps. She's sooooo tired by the end of the afternoon but just doesn't give in. She also does preschool every morning.
Her behaviour is a bit up and down too which is understandable but it's more so all changed since starting preschool and new baby. Same with my 20mo too really. But different age = different development obviously.
It's just when it's effecting them it's hard not to be effected. It makes them moody, not listen, emotional as am I!
A bit of a blah post, sorry!
