Flea infestation and my baby has bites all over

So I posted a weekish ago about the fleas in my house. It’s an apartment and there is no yard. We have 2 dogs and got them from house sitting a different dog.

We have never had fleas before. So anyways we didn’t realize for a while and by the time we did they were BAD. everywhere. In our bed. Constantly crawling on us. Well we bought flea medicine waited a few weeks thinking they would get better and only got worse again. The vet was like oh sorry. Because we bought it from them.

So we went and got some from the pet store and it actually helped a lot. They got wat better and I stopped seeing them (also washing our bedding every 2 days still and vacccuming every singe day sometimes twice a day.

Anyways now I’m finding bites on our 1 year old again. One on her face a few on her back and 2 or 3 on her arm. It makes me cry. I have no bites now (I had a lot when they were bad) I thought they were finally gone. I am so defeated and feeel like such a bad mom. I was told not to flea bomb since we have 2 dogs we have no where to take them and no yard. Also I am pregnant . Idkcwhzt else to do
