Loads of great advice here.
Try and walk as much as you can with the pram.
You don't have to have two slices if toast, just have one. Slice toast with peanut butter, hard boiled egg and an apple is a great breakfast.
Count your liquid calories... No lattes, coke, alcopops.
Try reducing pasta and bread, makes a huge difference.
Make soups with veg and lentils, filling and very healthy. You can have two bowls for lunch.
Cottage cheese, chopped fruit, sprinkle of granola.
Dont buy the junk, snack on dates if you fancy a sweet.
Drink water. Drunk water. Drink water.
Good luck op, it's hardbut you can do it!
