Sarah, I just checked the baby expo website and it said that there are bottle heating facilities.
You’ll find the Pigeon Mag Parenting Room to the right of the main entrance. It’s a quiet, private spot where you can feed and change your baby. It has facilities to warm bottles or food, as well as for washing bottles. There is also a qualified childcare nurse in attendence to answer any questions you might have.
btw the huggies site had buy one/get one free coupons for the baby expo on it last week.
