Not attracted to my husband anymore

We’ve been together 7 years, married for 4 ( today’s our anniversary) and unfortunately I’m not physically attracted to him anymore. We had a baby earlier this year and both put on a lot of weight and went thru lots of trauma with a NICU baby. We haven’t had sex since I was around 5 months pregnant and I don’t even want to. I mean I do but not with him. I’m super horny but he doesn’t make a move and I’m not going to either so we’re sorta stuck in limbo. And just thinking about it now the physical attraction just isn’t there. Any tips for sparking the flame back up?
