Very overwhelmed at the thought of returning to work in a few weeks.Have two dds 4 and 7 months.Husband works away during the week.Baby not a good sleeper.Still breastfeeding.Managing to get everything done that needs to be done but absolutely exhausted at the end of the day to the point that I feel shaky.I have an Underactive thyroid which contributes to the tiredness.I am so worried about how I will cope when I go back as I know I found it very tiring when I was pregnant.I feel when I'm at home I have more patience but when I'm tired from work (a teacher) I don't feel like I'm being the mum they deserve.There is an option to job share and we could afford it but hubby thinks we are better to have the extra income.Any advice welcome.
