9 months postpartum

I’m 9mo pp and for the past month I haven’t had an appetite to eat but I feel hungry.. when I go to eat I feel like I can barely eat. I started working 3rd shift 3 months ago 10p-6a I have my son during the day while dad is at work Tues-Sat 8a-6p by the time he’s out and gets home I don’t have much time til I have to work it’s hard to nap with having the baby all day I thought maybe this could be a reason why my appetite has been poor. Any tips to help increase appetite? Anything that has really helped you personally. ?
