Re: Weight gain
Not to worry. You can't overfeed a breastfed baby, because the baby is in charge of the feeding, not you. When he's no longer hungry, his sucking will slow down and become gentler, and the milk flow will slow way down or stop. This is totally different from the way bottle-feeding works, where the adult is in charge of the feeding and can easily and unintentionally encourage a baby to take just a little more and finish a bottle. Also, when a bottle-fed baby is done eating, but still needs to suck for comfort, the bottle continues to deliver the same rapid flow of fluid.
It's very normal for breastfed babies to gain weight extremely quickly in the early months. Many gain a pound a week during the early weeks/months. But as a breastfed baby becomes mobile, and starts putting calories into motion instead of packing them on as fat, weight gain slows way down.
