Returning Member - 3rd time a charm?

Hi everyone! I started on my fitness pal in 2012 at 155 lbs and finished at 137 lbs in 4 months. I went on vacation for a 1 week and one bad choice after another lead to more weight being gained. I also stopped logging and little by little stopped exercising. Several years later passed, new home, career promotions I ended up at 175 lbs... then gave birth to my first born in 2016 ... weighed 185 lbs... and now just gave birth in 2019 to my second child .. now I’m at 199 lbs!! Ugh... This is my 3rd attempt to seriously doing this again... it worked for me once before. Only this time I have kids. I would use excuses of my long work hours and not having having enough time to meal prep. Now I have no excuse. I want to take advantage of quarantine time and not sure when I will be returning to work. I don’t have any workout buddies or group of workout “girlfriends” that help and support me in this. This is literally the peak of my weight gain... would love some helpful advice to stay on track and and not fall off again. Even tips on ingredient must haves or snack must haves.. thanks! Anyone else struggle and succeeded in returning to fitness pal?
