DD is 2 weeks old now, and I'm on my own with her and DS who is 3 and a half most of the time.
I've found I have to leave her to cry whenever something urgent needs doing - getting food, having a shower, getting DS in bed etc. but she is feeding most of the time and I feel that both DS and the house are being neglected.
I've got a sling I'm going to start using if my sleep-deprived brain can figure it out. 
Other top tips please?
