Mash potato for 5 month old??

[Cunnyfunt18]

Could I mash a potato with ds's formula in to a smooth puree?

My daughter is 5 months tomorrow and she's been on puréed food for a good 5 weeks now, I've got a few different combinations of veg puréed in the freezer in pots, potato and pea, sweet potato, carrot and parsnip, sweet potatoes and broccoli. Basically I see what veg I have and combine them together!
Currently she has - 7/7.15 am a bowl of porridge (made up by 2 tablespoons of smooth porridge oats with about 3oz of formula milk)
She has the rest of her bottle as a drink usually 2/3oz
10am some mashed banana about 1/2 a one, 5 oz bottle
12/12.30pm a bowl of puréed veg, a pot of puréed fruit
1.30ish a 5oz bottle
4.-4/4.30 a pot of puréed veg, then either the other 1/2 of her banana mashed up or a pot of puréed fruit
5.30 ish a 4oz bottle
Then 6.30 ish bedtime 5/6 oz bottle

@Gorbie sounds like little ones got a fantastic appetite I'm gonna steal some tips lol my DS's routine is -

7/7.30 8oz bottle of formula
10/11 ish few teaspoons of baby porridge
2/3 ish another bottle
6 dinner which is usually pureed veg
Last bottle 9 and then into bed
