Just need some advise even though I’m aware there is no right or wrong way!
LO is just 6 months and on 3 meals a day, due to him not being interested in finger food it’s all purée food but I think no sooner I’ve finished feeding him in getting him next meal ready! For example
7am - 7oz bottle
10am - porridge with 5oz bottle
1pm - x5 ice cubes worth of veg plus dessert
4pm - 7oz bottle ( not always)
6:30pm - 5 ice cubes worth of veg plus dessert
8pm - 7oz bottle
Someone told me to keep feeding until he stops opening his mouth but I scared he won’t stop as he’s always been a greedy baby! 
Any suggestions would be greatly appreciated
Thanks
