I'm a 'double' parent to four year old DD1 and six month old DD2. DD2 has just had a massive sleep regression. I'm grieving for the loss of DH who died in June and so cannot handle sleep deprivation. I just can't. With DD1 I fed on demand, got up every hour etc. I never let her cry. I am wracked with guilt but I can't do same for DD2. I think I need to sleep train for all of our sakes. How do I dp this without damaging DD2? She's breastfed and about to go into her own room. Help[sad] [sad] [sad] [sad] [sad] [sad] [sad]
