First time mom

Miranda

So my 5month old daughter is having teeth poke through and she eats but she spits it all up afterwards and it's clumpy idk if this is normal she is also not really running a fever and on top of it she is constipated. She won't sleep at night and I'm pregnant with baby #2. My man tries to help but we both are new at this and it's starting to get hard someone please help us. I asked her doctor and she told us to give her medicine but she won't take it no matter what we do.
