Yeah, if the people you're talking to aren't supportive of what you're doing, don't talk to them about it. Come here! We'll support you.
DD3 has taken maybe 5oz total from a bottle. She's now 14.5 months old. If I go out she'd take just enough from the bottle to hold her over. Now that she's on a sippy for milk, there's no worries. If I could be there, why on earth would I give a bottle? The breast is faster, a better delivery method and is less work!
I find it funny when people say "they're manipulating you". Really? Manipulation? At this young age? The truth is they only refer to these higher, emotional abilities when babies do something inconvenient for adults. There are no accusations of empathy for example. Obviously that's too complicated for a baby.
Young of animals prefer to be with their mothers. Mom means food. Mom means safety. Mom means warmth. Mom means reassurance. Mom means love. Mom means survival. Why wouldn't they want to be with their mothers?
