Hello

My DS is 10 mo now. I breastfeed him but when I'm at work his nanny gives him formula as well. This makes me feel really bad but I can't express enough milk for him. When he's one year old I'd like to wean him from breast milk and formula but I'm not sure if it isn't too early. Im worried if Ill be able to provide him with all the necessary nutrients.
His tipical day now is
5am breast milk
8 am porridge- water based
10 -bm
13- veggies, meat, groats
15-bm
18- cereal- water based, fruit
20- bm
23-bm
2-bm- only a little so I think its more habbit than hunger
Do you think I should change anything for now? When I'm at work my LO gets formula instead of bm so I'm happy to feed him at night but I don't think Ill be able to stand it for much longer. And I strongly believ that formula is unhealthy and I wouldn't warn to give it to my LO for much longer.
Thank you for any advice.
