Bit of advice please. I'm due in February and currently trying to plan/buy everything. I had planned to use the MAM bottles and was buying a set to include steriliser and breastfeeding pump. I had also planned to buy the tommee tippee prep machine as I was advised by many this would save so much hassle and time when preparing formula. I've now found that MAM do a bottle warmer and I'm struggling to see what the difference is aside from the size and price! any help would be much appreciated!
