Hun, it's ok, you are doing ok!
Your baby is still very very young, this midterm will not break her sleep habits, I promise.
Do you think you can just roll with it for the midterm time and then she will be a bit older and we can look again at how to put her on a good routine?
Did I get it right that she is still sleeping well in the morning in her baskets but doesn't manage to go down for the other naps? What do you do then? Have you tried putting her in a sling? Will she sleep in the pram? Maybe you can aim then to be outside for her naps? Don't know if it's raining a lot right now in the UK...
