Hi. I was determined to wait until my LO was the full 6 months before starting solids but really wasn't expecting that he would be SO demanding. From prob 4.5 month he went haywire every time he saw me eat. Even if he had just had his milk (and I never let him drain a bottle, always made sure there was more than he would drink so I knew he was full) he would see my food and go APE! So for an entire month I could not eat in front of him, it was just about impossible. I would pop him in his play pen for a second a dart to the kitchen, shove whatever I could grab in my mouth and chew fast before running back to him - crazy! If he saw me chewing he went mad.
Eventually 5.5 months I just gave up. I felt like I was totally torturing him and making myself ill from not eating properly. I could not bare the screaming any longer and just let him have some. He hadn't increased his milk he wasn't waking at night hungry but he knew full well there was some kind of food being withheld and he was angry about it. It was totally not how I planned to wean at all.
If I did it again, I'd still wait, still starve myself for that month and prob still give in and let him have solids 2 weeks early. If you do start early do keep in mind the guide lines are there for good reason, their digestive system is more ready when they are older, and certain foods should be avoided prior to 6 months which makes it a bit harder to watch what you are giving too.
