hi all...my DS is 11 weeks old and weighs 6.67 kilos. he currently feeds every 3 hours during the day and 4 hrs at night. however he posits sooooo much at times that i think he may have thrown up his whole feed sometimes. there are times when circumstance stretches him to 3.5 hrs between feeds, or if he is sleeping during the day then yes he'll go to 4 or longer, but if i did want to start a 4 hourly feed routine with 6 feeds a day instead of 7 how do i know when he is ready for that, will he show me the way or do i need to train him? thanks.he's breastfed for most of those feeds by the way.
