Many body changes take place during pregnancy in order to nurture and accommodate the growing baby, and to help baby out during delivery. Among other things joints loosen, blood flow increases, sleep pattern may change and something called nesting instinct happens.
Also, there might be some weight gain but in the great scheme of things is usually inconsequential.
After my baby was born in the last day of August, and the tiredness of natural delivery was over, and the episiotomy healed and I started feeling like the person I had been before, I found all those loose joints, retained fluid and stretched muscles a bit pointless. Also, I found that baby care is demanding to say the least and my back and arms are feeling the pressure.
So I joined back the gym next door I had been attending for nearly a decade. To regain strength and flexibility, and to make all those diaper changes and lovely cuddling pleasant way after baby is clean and asleep in her cot.
And who knows, there might be some inconsequential weight loss too. Or so every person I've told about my plans seems to hope for.
