Yeah, my baby also stared obsessively at me eating, at that age. Still does! I still waited until he was six months old. And it turns out that his interest in me eating does not remotely translate to an interest in him eating - we've been working on weaning for about 8 weeks now and he remains sublimely uninterested in any form of finger food or any purée of any consistency, delivered in any manner. I have lovingly prepared every imaginable form of baby soup, yogurt, curry, pancake, muffin, scrambled egg, fruit, porridge finger and steamed vegetable, and I can't even remember what else, and then equally lovingly watched them all be hurled on the floor with startling efficiency.
Also, it's an epic messy faff.
Also also, he was apparently so unsettled by the mere suggestion that there might be some form of nutrition other than boobs that his sleep went completely out of the window and he now won't go in his cot at all, screams hysterically if put there, and essentially wants to be within touching distance of a boob the whole time. Preferably actually touching it. Or maybe just sort of half latched on for convenience... And he's not slept for more than two hours at a stretch since we started weaning. Suffice to say, he does not seem to be a fan of solid food, no matter how much he enjoys seeing other people eat it!
