Onto week 3 of solids. The first few days after Farex for brekkie he slept a couple of hours solid. On the following days where I gave him vegies he slept for 20-45 mins. The first night I gave him vegies (instead of earlier in the day) he woke earlier than normal. I'm now off Farex as his eczema has flared so he's had apple for brekkie and sure enough only slept for 20-30 mins (not even a full sleep cycle!). he's nearly 6 months old and started solids due to the signs he was giving me. I almost wish he was on milk only again!! anyone else experienced this? it's driving me a little crazy.
