Spitting up...help please

lyny42107

We have a 5 month old little boy. He has been EBF since day one and due to health issues with me I had to start supplementing with formula. I am a working mom and I am pumping during the day. We started introducing solids into his diet two weeks ago. I am still nursing and pumping with one bottle of formula at night. Everytime he has the BM he is spitting up a lot, and he is also not wanting to BF for very long and ends up not getting satisfied as well as not being very happy.

 Does anyone have any ideas??? I was hoping to get to at least 6 months with him (similar to what I did with my daughter).

 Thanks!!!!
