What is relactation ? Is it possible to breastfeed at 5 months for a mother whose 5 month child is taking formula since birth.

Asha

My preterm ( 35 weeks) baby was started on formula since birth as it was an unplanned c section and then I tried to breast feed after 4 days due to my delay in recovery after c section. However, there was no milk supply and after trying before each feed he finally used to take formula as there was no milk supply. My child was also receiving light therapy due to jaundice. After discharging from the hospital in a week I was trying for 1 week but no supply. Every time I used to latch my child would suck for sometime then started nauseating. On second week postpartum, I suffered postpartum hypertension and started on anti hypertensives and I stopped trying for breast feeding as I used to feel too tired. My baby has been fully on formula feed since then. Baby is now 4 months old. However, I still wonder if I could breast feed her. Was it a big mistake to not tried enough initially. Is there a way to breast feed again but I had resumed my periods in first month of postpartum itself. Is that anyone with the same issue ? Can someone guide me ? I am a new mother and didn’t had any knowledge regarding breast feeding. I had unplanned c section due some complications. I don’t have a lactation consultant in my area 🙏
