Hi, bit of an urgent one here. We are going abroad for 5 days on Thursday. Baby is 13 months old. He has 3 good meals a day, drinks water from sippy cup. He still has formula milk, but we've been reducing it. We will not have a steamer for the bottles abroad. Husband says take the steamer in the suitcase. I say this is silly idea. I think we should use the opportunity to wean him off bottles and formula onto cow's milk from sippy and normal cup. What do you think?
