Hubby wants us to go out for a meal soon and i was going to express so his mum can look after Isobelle and give a feed if needed but how much milk should there be in the bottle? i dont want to go out and not give enough milk but i also dont want to leave far too much and waste it or give his mum the impression that she will need it all as all her other grandchildren were bottle fed, im not even sure i want to go for the meal yet and im stressing!!!
