Aw (((hugs )))) danaadell.
Your LO is about the same age as my Little Man, how many feeds/ how much is he getting from bottle? How long is your day/ how long are you away from him?
What I've done is BF in morning before I leave for work, he gets solids breakfast at the childminders, solids lunch at the childminders, sips of water and I BF on my return from work between 3:30-4:30. He then has some finger foods (some fruit/veggies in batons, for eg) with us at dinner time and BF and bedtime.
Would a schedule like that work at all for you?
