I started Otis on solids at around 5months, letting him dictated what and how much he wanted, he only has one meal a day (at 5pm) and the rest is breast (he still feeds around every 3hrs and still wakes during the night). Since today I'll be introducing an early feed as well at around 10am - this morning he hadn't eaten anything from 4am till 10:30am so I was getting worried and the HV advised that maybe I should try and introduce another solid feed, which I did and it went down a treat.
Personally I would just say go with the flow and just do what you think is best for your baba, besides they'll let you know if they are ready for solids.
