4 months pp and i can not budge past 160 pound mark!!

Suggest something.......... i try and stay at my calorie allowance sometimes i go over but not by too much i exercise regular 6 - 7 days a week , back before i had bubs i lost a 7 kilo exercising heavily and eating very little i got my results but geesh if only i had the time to exercise and the space and i trully do not wanna eat very little again, i feel 1300 calories is too little but cos at the moment im a stay at home mum i put my Daily activities to light is that right?? i My diet may be the blame , id like to lose 8 kilo but it seems so hard to achieve it when im not getting any results ... thanks
