Not got any major tips, just that where weight comes into the equation, it's mostly through food that things are affected, exercise will have an effect but not by as much as people think- the human body is very clever and wisens to what we throw at it. One of the big reason we have survived so long as an animal is that we have learned how to store food in our bodies so we can survive famines. It means we can over eat and just store what we don't use rather than it going straight through us and for many of us we're better at this than others though unless we have medical concerns (eg thyroid issues) we all have the ability to become overweight due to storing food.

I would say to not get too stressed about losing weight soon after giving birth- partly our bodies try to keep the weight on us if we've just gone through a major bodily life change like that so we can take time to repair and rebuild and weight that our bodies don't require may be easier to get rid of when we're outside of the initial body-stress moment if that makes sense.

Keep a diary of what you eat, try to find times where you struggle and write down separately why and what you feel like doing and what you ended up doing weather or not you found a new coping strategy or couldn't stick to what you had initially planned. At the end of a few weeks of doing this and looking back each week to review, you may be able to see commonalities and put in to place things to help yourself; eg planning to eat where you feel most hungry rather than when you feel you should eat or planning to go for a walk when you feel hungry due to loneliness or tiredness.

Enjoy what exercise you do wherever possible. If you can do this, you are more likely to become better and stronger at it and find other forms of exercise previously beyond you feel easier and more achievable.

As long as you make life your priority and not food you should be OK, but IME it's when people feel so fixated and focused that little else mattered that they then feel depressed and it becomes a vicious cycle. Try to keep all things in relativity and remind yourself of what really matters and what's really important (food/weight aint it!). If you can do this every now and then and believe what you are reminding yourself, you may just find the weight falls off by itself.
