I'm in a similar boat. I had DD in December 2019 and was back in my pre pregnancy clothes a week after giving birth. Then I stopped breastfeeding around the first lockdown starting and ate my way to putting on 2 stone!
I started to get myself into a better situation, and then fell off the wagon massively, so I'm getting back on it again now!
I'm calorie counting (using my fitness pal) and trying to cut down on carbs (I'm a carb fiend!) , still having 1 takeaway a week as a treat.
I don't do gyms, but I have bought a weighted hula hoop so try to do 20 mins hula hooping a day (in front of the tv, always multi tasking) I also do you tube work outs when toddler is sleeping
I dye my hair myself anyway, but had it cut last week and felt so much better. I also had my first of 2 microblading sessions for my eyebrows because my brows being "done" makes a huge difference to me (as well as less time filling them in every morning) and I get my nails done every 3 weeks which is a lovely treat, and 1 less task for me.
I stick a face mask on once a week (either when the toddler naps or after she's down for the night) and I'm using better skincare as it's been battered by the lack of vitamin D, shit diet and hormones post DD.
For clothes, I'm still ordering online to try on at home. Buying basics - good jeans, t shirts, sweaters, bras and knickers. Then throw in the odd pretty dress. Some have been a disaster and is clearly lost the plot when ordering, but some have been keepers!
I'm not saying you need all of this, but it's just what I needed to get my backside in gear and feel better about myself.
