This may be outing but I just need some outside views - my DS was born in January, my dad passed away in march after a short illness and I've been trying my best to care for my son and grieve, around may my husband's shift changed to 5am-1am and I don't really sleep as thats when I tend to grieve and such about my dad (I guess because it's the only time I get to myself) and I was finding it really difficult caring for my son on less than 2 hours sleep so now when my husband's at work my mum comes up between 10-2 just to cover a feed so I can get some sleep. This is going to continue when I go back to work as I'll be working 9.30-2.30 but when my mum isn't here, DH and I split childcare, I just wanted to know if this was okay or am I being a shit mum to my baby.
