Oh honey.....

Adam has always gotten up at night.... he's great with all the kids... Even when breastfeeding, he would bring bub to me, cuddle us while we fed, and then put bub back (if i let him, i often co-sleep!)

But Adam can fall back asleep really easily, and it takes me hours... so if Ad gets up and gets me bub, I can do it half asleep, and he can go back to sleep fast, so it worked well for us.

Maybe Shell could arvo shift with Jazz?? Have her fed, and take an arvo nap. Let Shell know that without it, she'll have to help at night instead, cause you need to sleep at some point!!!
Adam done this for me when I had to get up 3 times a night to pump for Kane, even though Kane was sleeping through!!

She needs to compramise somewhere hon....Good luck...
