I had a serious coffee habit before being pregnant and mainly to cope with how little sleep I get with my children. Haven't had much due to feeling sick but now I'm feeling better it's really hard not to reach for a coffee when I'm exhausted. I've been up all night with a sick child and yesterday was similar and I ended up having more caffeine than I should then worried about it all night! How risky is having too much caffeine for the baby?I've looked it up and seems to be a risk of miscarriage is that right? Any tips for staying awake under extreme circumstances ( one of my children is disabled so no chance of sorting sleep as it's unavoidable issues).
