HI Abigail,
When i was pregnant with my first i was looking at an all singing and all dancing steam steriliser. My mum turned round and offered to buy the steriliser so i went with what she got me. Well it was a microwave one and its excellent by tomme tippee, get rid of the rubbish bottles and use avent. you wash up and rinse your bottles add an inch of water in the well shove it in the microwave for 5 mins (careful they are hot when just done) take it out or leave in the microwave until needed. a steam steriliser is always on show cause they are to big to pack away. you dont need sterilising tablets or fluid and it works in exactly the same way and costs half the price, i am going to be using mine for baby number 3. dont forget when you go away do you want to lug around a heavy steriliser, you have to remember all these things need to go with you for the first 6 months.
