I've just started trying to introduce my nearly 5-month-old to a bottle of formula a day (just so that I get a break). He was fine taking a bottle of expressed milk in the early days but I let the habit slide and now he won't take one. I'm finding it painful, frustrating and incredibly upsetting every time I try and am wondering if I might have more luck coming back to it when he's started weaning and is used to food coming in different forms than just the boob. Or is the answer just to persevere and hope one day the sobbing (from us both) stops?
Would appreciate any advice
