Exhausted 16mos PP

[MissingTheMoonlight]

For the last month or so I have been absolutely exhausted. Far more tired than even the first few weeks post partum. Struggle to keep my eyes open during the day at times.
Yesterday I had 2 naps and still felt awful. Last night I had 8 hours (broken) sleep and was a zombie all morning.
I'm not sure if it might be because my 16mo co sleeps and nurses all night; I had been coping fine with this but now it seems I'm not.
I spoke to the GP who checked my iron, B12 and Vit D. All fine except Vit D slightly low.
I eat well though we don't have dairy, egg or fish in the house as DS is allergic.
Periods still not back but I think they're on their way as I had cramping last week.
Anyway... anyone else shattered with a DC this age? How can I get my energy back?!

Take vitamin D tablets. I felt the same when I was about the same time pp. My vitamin D was 50, which is just borderline low. About a month of high potency vitamin D and I started to feel much much better.

Oooh @minutopia thanks for replying. I started taking high dose vit D yesterday so fingers crossed it starts kicking in soon.
