6 months regression?

maria

I'm not sure if what we are going through is called a 6-month regression, but my baby is waking up every 1.5 to 2 hours during the night and starts crying. I find myself picking her up so as not to wake my 3-year-old boy who is sleeping with us in the same room. Is this going to last long? I don’t want to build habits such as eating this much during the night as I’m breastfeeding her, and that’s very tiring. Any tips to help?
