Spoon feed is anyday better... however if you are keen on using bottles tgen go fir tge one thats anti-colic... i have used Avent anti-colic ones n they have worked well.. also between 1.5 to 2 years the bottles have to be weaned off... n milk should be had from a glass... to avoid issues with the teeth... i always followed up milk feed with water post 6 months  so that it rinses off the milk left in the mouth.. there by protecting the teeth... hope this helps..

agree with <font color ="#3b5998"><b> @6372be89649d83001690490b </b></font><font color ="#3b5998"><b></b></font> use spoon..

Always spoon...bottle feed leads other health issues so try not to opt it.
