Fitting supper into a 9mo's diet

[harverina]

My dd, 9mo, is currently on 3 meals per day. We do a combination of blw and spoon feeding, which seems to suit us well.
I suspect my dd is going through a growth spurt at the moment. She is breastfeeding more and hoovering her solids! A few nights ago I gave her porridge in the evening as she woke up and just didn't seem satisfied with a breast feed. She devoured it all. So, I have decided to offer a supper every night from now on. I think I will stick with porridge, though any other healthy suggestions would be welcomed. My problem is when to fit the extra meal in. Today we tried bringing lunch and dinner back a bit...so lunch at 11.45am and dinner at 4.45pm. She then had porridge after her bath at 6.15pm. I then breastfed her. She has not taken as much milk as usual but does seem more settled. Is this Ok? My dd feeds roughly 5 times per day.
Anyone have any insight into this?
Your opinions will be appreciated!
Thanks

As an aside, my DD is allergic to milk and eggs.

DD is 8.5 months and has 4 meals a day. We also do a combination of purees and finger foods. She is FF and takes 3 bottles a day. Her eating/drinking schedule is as follows:

7.30 - 8oz milk
8.30 - breakfast - weetabix made with formula
11.30 - lunch (150g main meal plus 100g pudding)
2.30pm - 8oz milk
3.00pm - afternoon tea (100g meal plus fruit pot)
6.30pm - dinner (150g meal plus fruit pot or yougurt
7.30 - 8oz bottle

to a certain extent we have had this eating schedule foisted upon us by nursery as DD attends 4 days a week. DD was skipping the afternoon tea meal and just having milk at 3pm until about 3 weeks ago when it became clear that milk was just not cutting it for her any more. Her main meals are usually protein based - shepherds pie, chicken stew, fish pie etc. Puddings are either yoghurt or fruit purees. At nursery they some time give cookies for pudding in the afternoon as a treat.

I think it is natural that they start replacing milk feeds with solids as they get older.

Thanks ThesugarPlumFairy. Hadn't thought of afternoon tea, what a great idea!
