Oh you are not a rubbish mum and must never think that!!
So sorry to hear your LO has an ear infection
how horrible.
I hope you get some sleep one way or another during her illness.
Try not to worry about routine, you'll either get back on track or this illness will work in your favour to set up a new routine as that happened with my DS a few times. it was when he slept a super long 2.5hr nap during illness that he dropped his nap cold turkey so you never know!
