my fiance just doesn't help at all with our son anymore at night , he's 8 months now and still isn't sleeping through the night. But then tells me I shouldn't let my son sleep in the bed with us . Like shut the hell up if you're not waking up to get him or at least help. If you want him to sleep in his crib then you wake up and get him . I'm 6 months pregnant so I have scoot out of the bed every single time he wakes up and to put him back inside his crib so no , plus he sleeps longer while he's in the bed , that way we both can get some sleep . He makes me so mad and then my fiance wakes up the next morning talking about how tired he is like wtf ?? you slept all damn night . ugh I'm just irritated
