im just over 7mths with my second baby. I have a 3 yo toddler, husband away etc so im always feeling worn out. Ive just recovered from a cough and sore throat a few weeks ago but still had a little bit of a lingering cough but it was clearing and now im coming down with a cold-could this be linked with iron levels? I have been eating well and going bed early no later then 10pm.
