Last night's bottle went WAY better. The nipple he used didn't seem to make a difference, but we had a good idea earlier in the week and he tried it out. When she got hungry he prepped the bottle then gave her his finger to suck on for a moment, then switched in the bottle. Voila! She took it just fine! I guess the nipple feels funny or takes some effort to get going or something, but this little switcheroo worked out great! I came home to a snoozing baby in the swing and Daddy playing video games, much better than the screaming I came home to in the past.
