I started DS on solds just before 6 months and TBH he really wasn't very interested at first. He is now 7 and a half months though and is on 3 meals per day (and has been for a few weeks). He is generally least interested in breakfast and I do sometimes skip that if we have a busy morning. But our day goes something like this.

7-7.30am BF
8.30-9am breakfast
11am BF
12.30-1pm lunch
2pm BF
5pm BF
6pm dinner
7.30 BF

He started sleeping through the night right on about 7 months, so I figure he is now getting enough sustenance through the 5 BFs and 3 meals.
