Workouts for mommy pooch

I’m 19 months postpartum and have hardly had time to work out. I must have worked out less than 20 times since LO was born. I have prioritized looking after her, taking her places, house chores and work. I am not trying to reach my pre pregnancy weight. I just want to get rid of the small pooch I have so I can fit more comfortably into clothes. I haven’t bothered buying new clothes because I thought I would eventually fit into most of my old clothes. I don’t see the point in sizing up because it will be looser overall and longer just to fit the belly. I look 4 months pregnant. I don’t have a lot of loose skin, it’s just my insides are hanging out more. For a while I thought I had to do exercises for DR. I never noticed much of a difference other than realizing my core is weak. Anyone had success getting rid of the pooch? What type of workout helped? All tips are welcomed
