How much formula for a 5 month old

[Jaz78]

We are currently bottle feeding our 5 month old 5 times a day.

Four of her bottles are 150 ml and one 180ml.

Does this sound an ok amount to be feeding a 5 month old?

Yesterday we tried to up one of her 150 ml bottles to 180ml and since this has been bringing up milk left, right and centre, so I am now concerned that we are over feeding her.

Any thoughts or advice would be very much appreciated.

Also worth noting that she has many teeth in her gums on their way through so it seems that she is teething.

Ds is4 months.
Hes a big lad has 5oz 4x a day plus 2x 4oz if he's up at night plus a lil baby rice as originally hexwas having 8oz every 2hours and screamed if we didn't give him enough.

My 5 and half month ds has 4-6, 6 oz bottles a day plus baby porridge for breakfast and some times fruit pots or baby rice at lunch/tea time.
My ds is a big baby though and very greedy but I go with feeding him when he is hungry no schedule or routine just when he wants it!
