I avoided it last pregnancy until very rarely in second trimester and then a bit more in third trimester. This time around I seem to be relying on it a bit more (I do have diet coke but don't drink coffee or tea) as I've been really tired, working and have a toddler.
I can't find much on the internet - I tried not to have any until 2nd trimester but had a few cans in week 11, and now at 16 weeks I'm nearly back to 300mls a day which I'm sure is not great. I just wondered what the medical preofessional advice on the sweetner itself was - caffeine aside! I really will ditch it if it's not recommended.... but also, will I have done harm to the baby?? Thanks so much! (paranoid but slightly addicted!)
It is best that you reduce your consumption as your baby will experience withdrawals after the birth if you continue to consume such a large amount. Try some alternative drinks such as tea or even water.
