Jeez - do they ever stop giving out contradictory information! I've been really surprised about the inconsistency of advice from HVs since the birth of my son earlier this year. He's just turned 16weeks and is rapidly heading towards 17lb and is 98 percentile length, 91 percentile weight. Whilst I'm conscious he may need to wean earlier than 6 months, I'm not contemplating it until he shows signs of really needing it - would expect him to be unsettled, not sleep well, cry after full feeds etc. As everyone says, go with your instincts. On the bottle front, we use the closer to nature variflow with our little man. Agree that bottle feeding with him hasn't been the calmest experience, but it has certainly improved with perseverance. One of the main issues we had was that he was drinking so quickly he got terrible wind - gulping loads of air. In the last week or so this has improved significantly, especially with us having a more set routine and getting to him with feeds before he is really hungry / overtired. Don't know if that's any use - but good luck!
